Abstract:
AbstractThis paper describes the compressive crush behaviour of spheres of closed-cell aluminium foams with different diameters (6, 8 and 10 mm) and square tubes filled with these spheres. The spheres of closed-cell aluminium foams are net spherical shape fabricated via powder metallurgy methods by heating foamable precursor materials in a mould. The square tubes were filled by pouring the spheres of closed-cell aluminium foams freely (without any bonding). The compressive crush performance of square tubes filled with spheres of closed-cell aluminum foams were compared to that of the empty tubes. The results show a significant influence of the spheres of closed-cell aluminium foam on the average crushing load of the square tubes. The energy absorption in the square tube filled with spheres of closed-cell aluminium foam with diameters of 10 mm is higher than in the other square tubes. The spheres of closed-cell aluminium foams led to improvement of the energy absorption capacity of empty tubes.

Abstract:
Aluminium foam has been popular in engineering, and aluminium foam research has become a research hotspot. The strain–stress relationship of aluminium foam presents three distinct stages. In this paper, the mechanical behaviours of aluminium foam materials under dynamic and quasi-static compression are studied. The effects of density, strain rate and temperature on the dynamic mechanical behavior of aluminum foam were analyzed. Combined with the dynamic and static stress–strain curves of aluminium foam, the specific characteristics and the phenomena in every stage of the compression process were studied by high-speed photography and CT. The experimental results show that aluminium foam undergoes obvious collapse layerby-layer in the process of compression. The stress–strain curves include a considerable stress drop after the elastic stage. Moreover, the structural defects of the material will cause the plastic failure in advance, and the possibility of the existence of structural defects will be affected by the density. Under dynamic compression, with increasing density the strain rate sensitivity of aluminium foam increase, but with the temperature increasing, the strain rate sensitivity was decrease.

Abstract:
The implementation of aluminium alloy foam has more and more attention. Application of closed cell aluminium foam has made an impact in automobile and aerospace applications where crash energy absorption, vibration and weight reduction are obligatory [1,2,3]. The aluminium alloy foam is an advanced lightweight material providing high strength and stiffness at relatively low density. The technological use of aluminium alloy foam is difficult with the currently available technologies. In the case of open cell aluminium foams, the most common research areas for application are heat exchanger components, filters and sound damping elements [3]. The manuscript focuses on the manufacturing techniques of the aluminium alloy foams according to the application areas. First step is the investigation of the requirements for the application: what are the loads and the circumstances and why can we use aluminium foams. Second step is the knowledge of the producing methods of the foam or the component. And the last step is the investigation of the possible testing methods.

Abstract:
Different aluminum foam filling lengths were used to increase the bending energy absorbing capacity of the popularly used hat sections. Bending energy-absorption performance of the thin-walled tubes was numerically studied by explicit non-linear software LS-Dyna. First empty hat section subjected to quasi-static bending crushing was simulated, then structures with different aluminium foam filling lengths were calculated, finally energy absorption capacity of these structures were compared. Calculation results showed that, the internal energy absorbed and mass specific energy absorption capacity of foam filled thin walled structures were increased significantly compared to the empty sections. The reason of the improvement was mainly due to the contact of the aluminium foam and the structure. Aluminium foam filling is a promising method for improving lateral energy absorbing capacity of thin-walled sections.

Abstract:
The aim of this study was to investigate the potential application of metal foams in shell-tube recuperators. A356 aluminium foam was cast around the internal and external surfaces of a thin-walled copper tube to enhance heat transfer between separated water streams at different temperatures. The results demonstrated that the aluminium foam drastically increased heat transfer efficiency due to its large volumetric surface area and high thermal conductivity. In the shell-tube foam recuperators, a maximum heat transfer efficiency of 48.1% was observed, compared to only 12.2% for a single copper tube without metal foam. The pressure drop across the external foam increased with the flow rate, from an average value of 1.19 kPa at 1.0 L/min to 7.36 kPa at 3.0 L/min. These findings suggest that metal foams have great potential for use in shell-tube recuperators, which could significantly improve the efficiency of heat transfer in various industrial and engineering applications.

Abstract:
Lightweight, robust, and anti-rust properties of aluminium foam might be a solution for reducing the effect of traffic accidents and for minimum fuel consumption. This research investigated the crashworthiness of vehicle crash-box filled with aluminum foam by varying its cross-sectional structure and its loading angle such as 0°, 10°, 20°, 30°. The variations consisted of structures for example single wall foam filled and double wall foam filled. The material used to construct the wall was Aluminum Alloy 2024 and Aluminium foam. The finite element model using Abaqus CAE Software was operated for both designing the crash-box and analyzing its crashworthiness. Some parameters were determined To obtain the best crash-box design, the finite element analysis was carried on total energy absorption, specific energy absorption, maximum load, average load, and crush-force efficiency. Double wall foam filled crash-box was shown to have better energy absorption ability and this structure of crush box is considered fpr vehicle structure in future.

Abstract:
Aluminium dross is a hazardous industrial waste generated during aluminium production. It contains metallic oxides of aluminium and magnesium, other phases (aluminum nitride), and residues of fluxes and salts from the melting process of aluminium. Discarding this by-product is considered an environmental and economic challenge due to the high reactivity of dross with water or even air humidity. After removing the hazardous components from the as-received dross, one of the optional approaches is to incorporate the treated dross into construction materials. Dross is applied in several types of research as a secondary raw material source for alumina, clinker, cement or glass-ceramic production, but only a few papers focus on the usage of dross as a foaming agent for foams. Even fewer research are reported where dross was applied as a basic component of foam glasses. In this work, foam glasses were produced completely from waste materials: Aluminium dross, container (SLS) glass, and cathode ray tube (CRT) glass. The research holds several specificities, i.e., combining two industrial waste materials (CRT glass and dross), and adding an increased amount from the wastes. The physical and mechanical characteristics were examined with a special focus on the effect of the foam glass components on the microstructure, density, thermal conductivity, and compressive strength.

In the present article, an attempt is made to develop aluminium foam indigenously. The experimental setup for the production of aluminium foam is designed and fabricated. Investigation are made into the use of dual foaming agents (i.e. TiH2 and CaCO3) along with SiC to develop suitable aluminium foams which can be utilized for various engineering products like load-bearing elements, crash resistance elements etc. The process is standardized to produce aluminium foam with specific density with minimum variability. This aluminium foam produced possesses a very low coefficient of friction. This work successfully characterized the frictional properties of the developed material. In order to define the Frictional properties of this material, a mathematical model which uniquely defines the frictional behavior of this modified Al-MMC foam has been developed.

Abstract:
Aluminium Lost Foam castings were made using gravity and counter-gravity filling techniques. Tensile strength was found to be most uniform in those castings which had been filled slowly from the bottom and where the metal front had remained stable throughout filling sequence. Pores containing carbon deposits were found on the fracture surfaces of all the castings made and this suggested that the defect was caused by polymer entrapment. A Saffman-Taylor instability was observed at the interface between Hg and a viscous glucose syrup which were contained in an analogue, that was used simulate the casting of Lost Foam moulds at room temperature. The liquid degradation products of the polystyrene patterns were also found to be viscous, although this was reduced by treatment with Br. Under the same conditions of temperature and velocity, the interface observed during the filling of a Br-treated pattern was planar whereas that of an untreated pattern was unstable. This demonstrated not only that the interfacial instability entrapped polymer degradation products, which adversely affected casting quality, but was probably of the Saffman-Taylor type.

Abstract:
This thesis focuses on closed-cell aluminium foams (ALPORAS and ALULIGHT) and on sandwich panels comprising these foams laminated with 2/2 twill carbon fibre (MTM56/0300) skins. The thesis experimentally and analytically investigates the response of foam-only panels (ALPORAS) to indentation with various indenter sizes and shapes; and also studies the behaviour of sandwich panels to contact damage caused quasi-statically or by impact. Quasi??static uniaxial compression testing is used to determine the mechanical properties of the foams (ALPORAS and ALULIGHT). It is revealed that the plastic collapse strength (σ* pl) obtained from the stress??strain curves is lower than the values predicted by the Gibson-Ashby theoretical model. This phenomenon is explained by the fact that the aluminium foams tested are imperfect, non-homogeneous and non-isotropic, and show a distinct cell elongation. Whereas, the Gibson-Ashby theoretical model was based on the finite element method applied to the response of a unit tetrakaidecahedral closed cell having flat faces. The experimental work shows that the deformation of the foam-only panels to indentation is caused by progressive crushing of the cell bands and by shearing and tearing of the cell walls. This thesis presents new analytical models for the response of the foam-only panels and estimates the applied deformation load in all types of indentation. By fitting the experimental load-displacement curves, the shear strength (τ* pl) and the tear energy (γ) are deduced. Compared to the literature, more consistent results are obtained for the shear strength (τ * pl) and the tear energy (γ) from all types of indentation. It is also suggested to determine (τ * pl) and (γ) through indentations with long punches (FEP and LCP), instead of hemi-spherical or cylindrical indenters, because indentation on enclosed areas shows some indenter size dependence. It is concluded that thinner panels are not suitable for the determination of the tear energy (γ) since the densification of the foam is achieved before the tear resistance is fully engaged. Another objective of this thesis is to study the response of sandwich panels comprising a closed??cell aluminium foam core and laminated with carbon fibre skin to quasi-static and impact local damage. Special attention is paid to the residual (remnant) strength in bending of the already indented sandwich panels (quasi-statically or by impact) up to the failure point. The remnant strength in bending is determined by carrying out four point bending strength tests. The local damage is located on either the compressive or on the tensile side of the sandwich panels. Thus, the capacity of the panels to resist transverse loads after they have been locally damaged at contact is investigated. The contact damage on the sandwich panels is experimentally simulated using spherical indenters. The quasi-static indentation is carried out at a low constant velocity (0.5mm/min) ?? the induced contact damage is found to be independent on the sample thickness but dependent on the indenter diameter. On the contrary, the impact test indicates velocity-dependence of the failure mode of the sandwich panel (i.e. skin breakage or punch through) which is found from the load-displacement curves. The results reveal that there is a correlation between the area of the contact damage and the remnant strength, and that the use of metal foam cores leads to high contact damage resilience of composite structures.

Abstract:
The current state of the art with regards to the production of metallic foams is reviewed, with melt-based processes identified as the most promising for cost-effective large-scale production. The potential for metal carbonates as an alternative to currently-used titanium hydride foaming agents is explored, with calcium carbonate identified as the most suitable. The influence of a range of material and processing parameters on the stability of metallic foams in the molten state is discussed, and current methods of controlling melt viscosity and surface tension are reviewed. Characteristic features of the compressive deformation of metallic foams are described in the context of use as an impact-absorbing material, with a review of work in the literature linking the bulk mechanical properties to details of the cell structure. Calcium carbonate is found to be a highly effective foaming agent for aluminium. The foams obtained have notably finer cell structures than can be achieved in foams produced with titanium hydride, coupled with enhanced stability in the molten state. This is attributed to the presence of a thin continuous surface film of metallic oxide that counteracts the effect of surface tension. This film, combined with the finer cell structure of the calcium carbonate-based foams, is found to significantly reduce the rate of gravity drainage of the melt. The formation of the thin oxide film during foaming gives rise to a number of artefacts on the cell surface, including stretch marks and tear bands. A range of chemical and surface analysis techniques are used to identify the chemical composition and thickness of the oxide film. The distribution of refractory particles in the cell faces, which are commonly employed to stabilise molten foam structures, is found to be highly non-uniform in foams which undergo significant gravity drainage of liquid metal during the foaming process. Experiments in which the concentration of particles is varied demonstrate the importance of their effect on the melt viscosity in addition to their known role as a surface stabilising phase. The effect of alloy content and foaming gas on the stability of standing molten foams is also investigated in the context of other foaming processes. The formation of an oxide film on the surface of the cells is shown thermodynamically to be a necessary step in the production of low-density aluminium foams with a calcium carbonate foaming agent. A temperature-dependent upper limit on porosity is observed. It is established that this is the result of inhibition of the calcium carbonate decomposition reaction by its products as the thickness of the surface oxide film increases. The effect of varying cell size, porosity and chemical composition on the thickness of the surface oxide film is derived. The rate of thermal decomposition of calcium carbonate is found to be dominated by the partial pressure of carbon dioxide, with particle size and small impurity contents having only a small effect. Compressive mechanical properties of the foams produced are compared with those of foams produced with a titanium hydride foaming agent and theoretical predictions. A reduced cell size apparently minimises the influence of point defects on the properties of specimens of finite dimensions. A significant difference in the shape of the stress-strain curves of calcium carbonate- and titanium hydride-based foams is noted, with the latter marked by extensive serrations. This difference is demonstrated to be independent of differences in cell size. Microstructural analysis of foams in various stages of failure suggests that this is due to differences in the distribution of refractory particles in the two foams, which is in turn a consequence of the reduced extent of gravity drainage of liquid metal in the calcium carbonate-based foams.

Abstract:
Aluminium foam has a range of properties that are desirable in many applications. These properties include good stiffness and strength to weight ratios, impact energy absorption, sound damping, thermal insulation and non combustibility. Many of these characteristics are particularly attractive for core materials within sandwich structures. The combination of aluminium foam cores with thermoplastic composite skins is easily manufactured and has good potential as a multifunctional sandwich structure useful in a range of applications. This thesis has investigated the flexural behaviour of such structures using a combination of experimental and modelling techniques. The development of these structures towards commercial use requires a thorough understanding of the deformation and strain mechanisms of the structure, and this will, in turn, allow predictions of their structural behaviour in a variety of loading conditions. ¶ The experimental research involved the use of an advanced 3D optical measuring technique that produces realtime, full-field strain evolution during loading. This experimental characterisation of strain evolution in this class of sandwich structure under flexural loading is the first of its kind in the world. The experimental work studied the sandwich structure undergoing four-point bend testing. Initial studies compared the behaviour of the aluminium foam structure with a more traditional polymer foam sandwich structure. The aluminium foam structure was found to have equivalent or improved mechanical properties including more ductile deformation and an enhanced energy absorption. An investigation was conducted on the effect of core and skin thickness on the metal structure and a range of flexural behaviours were observed. Analysis of the strain distribution showed a complex development including localised effects from the non-uniform cellular structure of the material. An understanding of the variation with size is important in establishing design methods for utilising these structures. In particular, it is desirable that finite element simulations can be used to predict behaviour of these structures in a diverse range of loading conditions. This aspect was considered in the second half of this study. An existing constitutive model for aluminium foam, developed for use in compression energy absorption studies, was used to investigate finite element simulations of the flexural behaviour of the sandwich structure. The FE model was able to predict the general deformation behaviour of the thinner skinned structures although the magnitude of the load-displacement response was underestimated. It is suggested this may be related to the size effect on the input parameter characterisation. The strain distribution corresponded well with the experimental strain measurements. It was found a simple increase in the material model input parameters was able to more closely match the magnitude of the load-displacement response while maintaining the appropriate strain distribution. The general deformation shape of the model with the thicker skin corresponded reasonably well with the experimental observations. However, further work is necessary on the element failure criterion to capture the shear cracking observed. The strain distributions of the model predicted this failure with high strain concentrations matching those of the experimental contours. The last part of the thesis describes a parametric study on the effect of the foam material model input parameters on the flexural behaviour of the sandwich structure model. An important conclusion of this work is that this material model for aluminium foam can, with some development, be utilized to provide a viable method for simulating aluminium foam composite sandwich structures in flexural loading situations.

Abstract:
Pure aluminium and aluminium-5wt % TiO2 aluminium foams were produced by powder metallurgy technique with the use of TiH2 as foaming agent. Two sizes of TiH2 were used: 20µ
m and 3µ
m. It has been confirmed that high level of compaction is the primary requirement in foaming. It was shown that hot swaging could be used as a method of compaction for foaming as it leads to values close to full density. Pure aluminium foamed at 675°
C and 725°
C leads to a volume expansion between 90-180 %. A model was developed for pure aluminium to explain the pore initiation and the resultant pore size. The model predicts a critical particle size for TiH2 below which bubbles could not form. The size appears to be in the neighborhood of 30µ
m for 675°
C and 6µ
m for 725°
C and is temperature dependent. Equilibrium pore size appears to be a function of TiH2 particle size and not affected significantly by the temperature of foaming. It has also been shown that depth effect, i.e. hydrostatic pressure of liquid metal, is unimportant in foaming process and can be neglected. According to the model, to produce pores of fine sizes, two requirements must be met: use of fine foaming agent and the use of high foaming temperature. Al-5 wt % TiO2 was foamed at 750°
C and 800°
C, i.e. at temperatures that yield viscosities similar to pure aluminium. The structure of foamed metal and level of foaming, 120-160%, was similar to pure aluminium. Unlike pure aluminium, internal reactions are dominant feature of TiO2 stabilized systems. Solid content of the system increases as a result of internal reactions between Al-Ti and Al- TiO2. When this change occurs, however, is not known. It is possible that the viscosity of the system may be four times of its original value.

Abstract:
Traction systems generate high loads of waste heat, which need to be removed for efficient operations. A new transient heat sink is proposed, which is based on salt hydrate phase change material (PCM). The heat sink would absorb heat during the short stationary phase i.e. at stations in which the PCM melts, a process accelerated by aluminium foam as it increases the rate of heat transfer within the PCM. When the train moves, the PCM is solidified via a forced convection stack. This creates a passive and efficient thermal solution, especially once heat pipe is employed as heat conduit. At the outset, the characteristics of the foam needed to be accurately determined. The foam was uncommon as its pore morphology was irregular, therefore it was scanned in a medical computed tomography (CT) scanner, which allowed for the construction of a three dimensional (3D) model. The model accuracy was enhanced by software, resulting in an extremely useful analytical tool. The model enabled important structural parameters to be measured e.g. porosity and specific surface area, which were crucial for the subsequent thermal and fluid flow analyses. A defect dense region was also detected, the effect of which was further investigated. Interestingly in the volume devoid of this defect, the porosity and specific surface area were uniform. A test rig was constructed that mimicked liquid cooling (or in the planned application, heat pipe cooling) in power electronics. At the core was a heat sink of salt hydrate PCM, impregnated within the foam. The sink with its current specifications (with liquid cooling) was able to absorb a thermal load consistent from a group of 4-5 IGBTs, which dissipated a low power of 20W per module during stops. The heating period of 1600-3500s per cycle meant the sink could be fitted to intercity locomotives. The foam increased the effective thermal conductivity by a factor of 24, from 0.45 to 10.83 W/m.K. 3D volume averaged numerical simulation was validated by experiment, which could be used to facilitate scale up or redesign for further optimization. As well as a support structure for the storage component of the system, the foam could replace conventional fins in forced convection, adding value to the potential manufacturer of the system. Heat transfer coefficient calculation incorporated the actual surface area that was derived from the 3D model, a first for metal foam studies. Results have shown a good Nu/Re correlation, comparable with other metal foam works.

Abstract:
The overarching aim of this work was to concentrate on the mechanical modelling and experimental characterisation of novel open-cell aluminium foam core sandwich panels for prospective use as an airplane wing skin material. A repeating unit cell 2D FE model was created to assess the mechanical behaviour of infinitely long, regularly tessellated honeycomb core sandwich panels. An analytical model using Timoshenko beam theory was developed to predict the Young’s modulus of a hexagonal honeycomb core; there is good agreement between the two models. A microtensile test procedure was developed to determine the mechanical properties of individual foam struts. A FE model of the as-tested struts was created, using XMT scans of the undeformed struts to define the geometry, to establish a method that compensates for grip slippage inherent in the testing of the struts. Strut deformation was described by a calibrated continuum viscoplastic damage model. The damage model was implemented into 3D FE models of an open-cell aluminium alloy foam core sandwich panel subjected to uniform compression to study the effect of varying the strut aspect ratio on the mechanical properties of the core. FE models of the panel subjected to three and four point bending were created to provide a virtual standardised test to assess the core elastic properties. The extent of structural damage in the panels was simulated for indentation loading indicative of a tool strike; an optimal strut aspect ratio was identified providing the best energy absorption per unit mass whilst ensuring core damage is detectable. The effect of morphological imperfections on the mechanical properties and extent of detectable damage of the core was studied. The shear modulus of the core was greatly reduced under the presence of both fractured cell walls and missing cells. The extent of visible damage was largely unaffected by either type of defect.

Abstract:
ABSTRACT A study is carried out on the production of aluminum foams via powder processing. The study deals mainly with the effect of TiH2 particle size on the process of foaming. Mainly two TiH2 particle sizes were used
namely 27,5 &
#61549
m and 8,5 &
#61549
m. Foaming experiments were carried out at temperatures between 675oC &ndash
840oC. The viscosity of the system is adjusted by controlled addition of Al2O3. The study shows that choice of foaming agent size is influential in the foaming process. With the use of fine foaming agent, temperatures in excess of 800oC would be required for successful foaming. The study further showed that the relation between foaming and viscosity was also dependent on the particle size. Viscosity of 2.3 mPa.s was found to be a limiting value for successful foaming with fine foaming agent. This value appears to increase with increasing particle size. An analysis is presented with regard to temperature dependence of foaming which takes into account the effect of particle size.

Abstract:
Abstract Especially, composites of aluminium metal foams are of high potential for lightweight applications in automotive, aerospace and general engineering because of their excellent ratio of low weight and high stiffness. To fulfill the industrial need for these new materials as soon as possible, a new integrated manufacturing process concept has been developed and studied at our institute. The new “easyFoam-process” concept consists of four basic steps: production of semi-finished parts via the powder metallurgical route, forming of the foamable semi-finished part into a near net shape by extrusion or any standard aluminium-forming process, coating of the surface by thermal spraying and foaming by inductive heating. Thus it’s feasible to provide a fast, continuous and efficient production of metal foam composites with highly reproducible properties, resulting in eminent advantages over current techniques for foam sandwich production in terms of degree of anisotropy, statistical spread in foam properties and production economy. This process is also the only one being able to produce a graded pore structure in symmetrical parts of PM-aluminium foams. The thermally sprayed coatings serve simultaneously as mould and as future multifunctional coating. In this paper, some results of our first study in coating the foamable Al-tubes and inductive heating the coated parts are presented.

Abstract:
Foams are one of the best solutions for energy absorption enhancement. Many types of materials can be produced in the form of foams, including metal and polymers. Among metal foams, the most advanced are aluminum based. They couple lightweight with good properties, not only mechanical, but also, for example, good thermal stability. Among the various aspects still to be investigated regarding their mechanical behavior, there is the influence of a hydrostatic state of stress on yield. Unlike metals, the hydrostatic component affects yields. Therefore different loading conditions have to be considered to fully identify the material behavior. Another important issue in foam structure design is the analysis of composite structures. To this purpose an aluminum foam has been examined (FOAMINAL, provided by IFAM within the 6th Framework Programme European Project APROSYS). The material behavior has been investigated by subjecting the foam to different stress state conditions (uniaxial, hydrostatic, pure deviatoric, and various combinations). Results obtained in various kinds of test will be presented: uniaxial compression, in quasi-static and dynamic conditions loading the components into a SHPB device, tension, bending, and shear loading. Moreover, composite structures were made by assembling the foam into aluminum cold extruded closed section tubes (in 6060 aluminum). All the results show that the energy absorption capability of the composite structures is much greater than the sum of the energy absorbed by the two components, the foam and the tube.

Abstract:
Recently, closed cell cellular metals have been gaining a very high interest due to their unique characteristic applications in various technology domains. They combine the advantages of a metal with the structural advantages of foam. Among these, aluminium foams have created a great interest due to their light weight structure and their various applications in the automotive, aerospace and allied industries. Aluminium foam possesses high stiffness and low density, it has good energy-absorbing properties making it good for crash-protection and packaging and it has attractive heat-transfer properties that permit to use these materials to cool electronic equipment and as heat exchangers in engines. However, its manufacturing techniques and characterization methods need more attention. The inadequate knowledge on the physical phenomena governing the foaming process does not allow to obtain products with repeatable characteristics. In this paper aluminium foams in various fabrication components were produced by applying the powder compact melting method. In particular metal powders (AlSi7) and powdered gas-releasing blowing agents (TiH2) were mixed and subsequently pressed to obtain a foamable precursor material. The resulting precursor was then foamed by heating it up to above its melting point. Experimental tests were performed to study the fabrication of aluminum foam components and with the extent of optimize the pressing parameters of the foamable precursor material, the foaming temperature and the heating rate during foaming. It was studied the effects of geometrical discontinuities in the mould (such as holes, restrictions, etc) on the evolution and on the morphology of metal foams.

Full text
Abstract:
The design of buried pipes, in terms of the allowable minimum and maximum cover heights, requires the use of both geotechnical and structural design procedures. The geotechnical procedure focuses on estimating the load on the pipe and the compressibility of the foundation soil. The focus of the structural design is choosing the correct cross-section details of the pipe under consideration. The uncertainties of the input parameters and installation procedures are significant. Because of that, the Load Resistance Factor Design (LRFD) method is considered to be suitable for the design of buried pipes. Furthermore, the interaction between the pipe structure and surrounding soil is better captured by implementing soil-structure interaction in a finite element numerical solution technique. The minimum cover height is highly dependent on the anticipated traffic load, whereas the maximum cover height is controlled by the section properties of the pipe and the installation type. The project focuses on the determination of the maximum cover heights for lock-seam CSP, HDPE, PVC, polypropylene, spiral bound steel, aluminum alloy, steel pipe lock seam and riveted, steel pipe and aluminum arch lock seam and riveted, non-reinforced concrete, ribbed and smooth wall polyethylene, smooth wall PVC, vitrified clay, structural plate steel or aluminum alloy pipe, and structural plate pipe arch steel, or aluminum alloy pipes. The calculations are done with the software CANDE, a 2D plane strain FEM code that is well-accepted for designing and analyzing buried pipes, that employs the LRFD method. Plane strain and beam elements are used for the soil and pipe, respectively, while interface elements are placed at the contact between the pipe and the surrounding soil. The Duncan-Selig model is employed for the soil, while the pipe is assumed to be elastic. Results of the numerical simulations for the maximum fill for each type and size of pipe are included in the form of tables and figures.

Full text
Abstract:
The ultrasonic treatment process strengthens metals by increasing nucleation and decreasing grain size in an energy efficient way, without having to add anything to the material. The goal of this research endeavor was to use machine learning to automatically measure cavitation area in the Ultrasonic Treatment process to understand how amplitude influences cavitation area. For this experiment, a probe was placed into a container filled with turpentine because it has a similar viscosity to liquid aluminum. The probe gyrates up and down tens of micrometers at a frequency of 20 kHz, which causes cavitations to form in the turpentine. Each experimental trial ran for 5 seconds. We took footage on a high-speed camera running the UST probe from 20% to 35% amplitude in increments of 1%. Our research examined how the amplitude of the probe changed the cavitation area per unit time. It was vital to get a great contrast between the cavitations and the turpentine so that we could train a machine learning model to measure the cavitation area in a software called Dragonfly. We observed that as amplitude increased, average cavitation area also increased. Plotting cavitation area versus time shows that the cavitation area for a given amplitude increases and decreases in a wave-like pattern as time passes.

ROTATIONAL RESISTANCE TEST OF A NEW ALUMINUM ALLOY PENETRATING (AAP) JOINT SYSTEM. The Hong Kong Institute of Steel Construction, June 2023. http://dx.doi.org/10.18057/ijasc.2023.19.2.4.

Full text
Abstract:
Aluminum alloy penetrating (AAP) joint is an improved form of the Aluminum Alloy Temcor (AAT) joint system consisting of one penetrating member, four short members, gussets, bolts and a U-shaped connector. The rotational resistance performance of AAP joints is investigated by a static out-of-plane flexural test. The specific experimental parameters include the gusset thickness (6 mm and 12 mm) and shape (circular and X-shaped). The differences between penetrating and short members in AAP joints are analyzed, and the influence of thicknesses and shapes of gusset on rotational resistance behavior of the joints is analyzed. The establishment of the finite element model of the AAP joint system in this paper considers the effects of bolt pre-tightening force, installation gap and friction between contact surfaces. The M-Φ curves and damage patterns are obtained by numerical simulation. The detailed comparative analysis between AAP joint numerical simulation and test results verifies the accuracy of the numerical model.
