Material selection is one of the main factors in the building structure. In this study, an alternative method was implemented using fractal analysis method. The use of this method can be used for cost savings and accident rates to identify the mechanical properties of each material. The purpose of this research is to study the time series resulting from experiments using piezo film sensors using fractal analysis and investigating the properties of different mechanical materials (poisson ratios) with different impact forces using fractal dimensions. There are four types of selected materials namely brass, copper, mild steel and stainless steel which is in round in shape. Different impact forces are generated by using an impact hammer and subsequently a vibration signal is obtained from a piezo film sensor. Using Matlab software, analysis using the fractal method was performed. The fractal dimension was obtained from the gradient values of the log-log plot and the fractal dimension was calculated for each impact force applied to each specimen. Then, fractal dimension values were compared using CES Edupack2012 for characterization of the properties of each material. It can be concluded that the value of fractal dimension increases when the impact forces increase too whereas a decrease in the poisson ratio occurs when the fractal dimensions of each material increase.

For the problem of mechanical properties of heterogeneous dissimilar metal welded joints, when analyzed by the finite element method, it is usually simplified into a “sandwich” material structure model. However, the mechanical properties of materials in different regions of the “sandwich” material mechanics model are different, and there will be mutations at the material interface. In order to accurately describe the mechanical properties of welded joints, the constitutive equations of dissimilar metal welded joint materials were compiled, and the constitutive equations of inhomogeneous materials whose material mechanical properties were continuously changed with space coordinates were established. The ABAQUS software was used to establish the “sandwich” model and the continuous transition model. The model is used to compare and analyze the crack tip stress distribution of different yield strength mismatch coefficients. The results show that the continuous transition material model eliminates the mutation of the “sandwich” model at the material interface and achieves the continuous change of the mechanical properties of the material. For the longitudinal crack, under the influence of different mismatch coefficients, the crack tip stress field of the transitional material model is deflected toward the low yield strength side. The compilation of constitutive equations for continuous transition materials of dissimilar metal welded joints provides a basis for the safety evaluation of dissimilar metal welded joints.

The significance of composite materials and their applications are mainly due to their good properties. This imposes the need for their recycling, thus extending their lifetime. Once used composite material will be disposed as a waste at the end of it service life. After recycling, this kind of waste can be used as raw materials for the production of same material, which raises their applicability. This indicates a great importance of recycling as a method of the renowal of composite materials. This study represents a contribution to the field of mechanical properties of the recycled composite materials. The tension mechanical properties (tensile strength and modulus of elasticity) of once used and disposed glass-epoxy composite material were compared before and after the recycling. The obtained results from mechanical tests confirmed that the applied recycling method was suitable for glass-epoxy composite materials. In respect to the tensile strength and modulus of elasticity it can be further assessed the possibility of use of recycled glass-epoxy composite materials.

Analogue material with appropriate properties is of great importance to the reliability of geomechanical model test, which is one of the mostly used approaches in field of geotechnical research. In this paper, a new type of analogue material is developed, which is composed of coarse aggregate (quartz sand and/or barite sand), fine aggregate (barite powder), and cementitious material (anhydrous sodium silicate). The components of each raw material are the key influencing factors, which significantly affect the physical and mechanical parameters of analogue materials. In order to establish the relationship between parameters and factors, the material properties including density, Young’s modulus, uniaxial compressive strength, and tensile strength were investigated by a series of orthogonal experiments with hundreds of samples. By orthogonal regression analysis, the regression equations of each parameter were obtained based on experimental data, which can predict the properties of the developed analogue materials according to proportions. The experiments and applications indicate that sodium metasilicate cemented analogue material is a type of low-strength and low-modulus material with designable density, which is insensitive to humidity and temperature and satisfies mechanical scaling criteria for weak rock or soft geological materials. Moreover, the developed material can be easily cast into structures with complex geometry shapes and simulate the deformation and failure processes of prototype rocks.

The usage of waste materials in making concrete gives a satisfactory solution to some of the problems related to waste management and environmental concerns. In the development of blended cements, some of the Agro wastes such as sugarcane bagasse ash, rice husk ash and wheat straw ash are used as pozzolanic materials. Few studies have been reported on the use of bagasse ash (BA) as partial cement replacement material. This research aims to study the physical and mechanical properties of hardened concrete prepared with bagasse ash as partial replacement material for cement are reported. The Portland cement was replaced with BA in the ratio of 0%, 5%, 10%, 15% and 20% of weight of cement. The compressive strength, splitting tensile strength and flexural strength of concrete at the age of 28 days were investigated. From the test results it was observed that bagasse ash is an effective mineral admixture, with 5% as optimal replacement ratio of cement.

In this paper, the authors analyse the impact of selected mechanical properties of materials on their erosive wear caused by a steady stream of solid particles. A wear process is a function of the material properties of two materials that interact with each other in a given environment, i.e. the construction material and the particles that cause erosion. Erosive losses occur upon reaching a critical condition of damaging an element of the material’s surface under the influence of kinetic energy that result from incident particles of an abrasive material. It is proposed that the critical condition that accompanies the formation of erosion losses should be represented by the toughness (U) and the specific work of the deformation of the sample in the tensile strength test (W). The study involved the following materials: NC6, 42CrMo4, 20MnCr5, and S235JR.

Food, energy and construction are the three main domains in which different uses of industrial hemp confirm the role and importance that agriculture has in human life. In the current context with an increased need for energy efficiency and environmental protection, the attention of scientists is directed towards the identification of ecological construction materials, and a sustainable way of life, where the circular economy must become part of people’s living habits. The objective of the research was to analyze the thermo-mechanical properties of hempcrete. The goal is to determine a point of reference for future studies that will aim to adapt the agreed compositions to the particularities of the raw material obtained locally. Measurements were determined through laboratory tests, performed on specimens obtained using, for the base material, the woody part of industrial hemp, and for the binder, a mixture consisting of hydrated lime and Portland cement. The results place the construction materials made from hemp vegetable waste in the group of heat-insulating products characterized by low specific weight and thermal transfer coefficients, according with conventional insulating materials, with values between those of polyurethane foam and autoclaved cellular concrete.

One of the methods of changing the mechanical properties of polymeric materials is by the creation of composites with various substances whose task is to strengthen and fill them. Thanks to the use of fillers, we can obtain new materials with interesting mechanical and chemical properties. Among the materials obtained, some of the features are often improved, while the others deteriorate. In this study, an attempt was made to obtain a polymer composite based on a PLA filled with macaroni chalcedonite in the amount of 5%, 10%, 15%, 20% and 30% by weight. The properties of the mechanically obtained mixtures were assessed. The tests show that the number of substances in the composite had a significant effect on changing the properties of the obtained material.

In this work itria stabilized ZrO2 based ceramics for dental applications has been sintered and characterized in terms of physical and mechanical properties. Nanostructured blocks were sintered at 1400 0C and microstrutured blocks sintered at 1600 0C. Both nanostructured and microstructured materials were characterized in terms of densification, crystalline phases, mechanical properties and microstructure. Fracture toughness and four point bending strength were evaluated and compared. For the nanostructured zirconia, the reduced grain size allowed the increase of its toughening capacity, generated from maximization of volumetric fraction of retained tetragonal zirconia particles. For this material higher bending flexural strength is related to induced nucleation of microcracks, increase of energy absorption during crack propagation and developed compressive surface stress. The fracture toughness obtained at nanostructured samples sintered at 1400 0C is approximately 20% higher when compared to microstrucutured samples. These results represent the toughening ability of nanostructured zirconia, originated from higher amount of retained tetragonal phase and grain boundary microcracks. The higher Weibull moduli in this case are indicative of material reliability improvement and these results are correlated to grain size and its influence at mechanical strength.

The paper deals with the polymeric fibre composite with the reinforcement on the basis of the waste from the process of the tyres recycling. The aim of the research was the use of the material of cleaned textile waste from the process of the tyres recycling. The secondary waste raw material was used as filler in the composite. The subject of performed experiments was the polymeric composite, whose continuous phase was in a form of a two-component epoxy adhesive (GlueEpox Rapid) and a discontinuous phase in a form of microfibers from the process of tyres recycling. The experiments results proved that the composite materials based on the textile waste from the process of the tyres recycling reached an increase of an impact strength, a tensile lap-shear strength and an elongation of the adhesive bond <br /> (to 2.5% vol.). The textile microfiller has a negative influence on the tensile strength and elongation of adhesives.

Substitute of the traditional materials with new plastic-based and composite materials is a trend in today's automotive industry. Mechanical properties of the composite parts are highly influenced by the composite production (material of fibers and their distribution, type and density of a filler). Knowledge of the specific composite material mechanical properties is necessary for CAD modeling and FEM calculations during the assembly design. These mechanical properties can be obtained by creating a composite structure in FEM software. However, the real composite may be different from the ideal FEM model (due to inaccuracies in its manufacture). Therefore, it is highly advisable to verify the modeling results by measuring of the real composite material properties. Identification and verification of the composite tube mechanical properties used in the hybrid car tailgate are described in this paper.

Polymer concrete was introduced in the late 1950s and became well known in the 1970s for its use in repair, thin overlays and floors, and precast components. Because of its properties like high compressive strength, fast curing, high specific strength, and resistance to chemical attacks polymer concrete has found application in very specialized domains. Simultaneously these materials have been used in machine construction also where the vibration damping property of polymer concrete has been exploited. This review deals with the efforts of various researchers in selection of ingredients, processing parameters, curing conditions, and their effects on the mechanical properties of the resulting material.

A novel optimization approach is proposed to extract mechanical properties of a power law material from its given experimental nano-indentation P-h curves. A set of equations have been established to relate the P-h curve to mechanical properties, E, σ y and n, of a material. Using the proposed optimization approach, convergence studies were carried out for the determination of the mechanical properties of materials. It was found that the mechanical properties of an elastic-plastic material usually cannot be uniquely determined using a single loading and unloading P-h curve. Thus a technique has also been developed to determine the material properties from indentation p-h curves using indenters with two different angles. This enables the mechanical properties of materials to be uniquely determined.

This study investigates the influence of the matrix material and the degree of prestretch of a knitted fibre structure on the mechanical properties of knitted composites with low fibre volume fractions. By embedding a flexible textile structure in an elastomeric matrix, composite materials are obtained that combine an interesting stress-strain behaviour with extreme extensibility and relatively high levels of energy absorption. Although this study focuses on the influence of the degree of prestretch of the knitted structure on composite properties based on rubbery matrices, reference materials based on highly cross-linked epoxy resins were also studied.

The selection of the appropriate polymer material represents one phase in the product design, both, in terms of data on the different properties of the material and for detailed assessments and selection of the best material for the selected product. In the material selection phase, it is necessary to define criteria related to the mechanical properties of the material (strength, stiffness, toughness). Another important item is certainly the stress-strain diagram by which the materials can be classified into certain groups, based on their mechanical properties. The paper presents a study of materials classification according to the following groups: Hard and brittle, Hard and strong, Hard and tough and Soft and tough materials, using the cluster analysis (k-means algorithm).

For nanoscale devices and structures, interface phenomena often dominate their overall thermal behavior. The feature scale of material interfaces usually originate from nanometer length and present a hierarchical nature. Considering to the limitations of the continuum mechanics on the characterization of nano-scale, the multiscale model featuring the interface could be very important in materials design. The purpose of this review is to discuss the applications of multiscale modeling and simulation techniques to study the mechanical properties at materials interface. It is concluded that a multi-scale scheme is needed for this study due to the hierarchical characteristics of interface.

For mechanical performance perfection of cement-based material, toughening materials are often added to the cement system, such as solid particles, carbon-based material, or other inorganic/organic materials. Compared with other materials, carbon-based materials have better compatibility and are more likely to form a cross-linked network structure in the cement system, which can significantly improve the mechanical properties of cement stone. In this review, a new type carbon-based material ZRJ-S1 was used as a mechanical additive to reinforce oil well cement. In this experiment, ZRJ-S1 was explored with microlevel scale and showed the thin-layer sheet morphology. With static mechanical-strength test, ZRJ-S1 reinforced cement-based material was found with excellent mechanical improvement when 0.05 wt% ZRJ-S1 additive was used, that is, compressive strength improved to 150.9% of that of control sample, splitting tensile strength improved to 134%, and flexural strength improved to 129.2%. Furthermore, the weight percentage superiority of ZRJ-S1 was researched by dynamic stress-train mechanical test and found the mechanical elasticity improvement in which Poisson ratio improved by 74% and formed elasticity modulus reduced to 65.4% when resisting to mechanical damage. The effect of ZRJ-S1 on the microstructure of cement-based materials was studied. As a result, ZRJ-S1 was found with the bridging effect for completion of cement-based material, crack deflection effect for controlling microcrack propagation, and pulling-out effect for preventing immediate fracture of cement-based material itself. Then, using about 0.05% of ZRJ-S1 achieved the accelerating effect on hydration, the speed of the cement-based material, in which more C-S-H gel was formed. Moreover, adding of microscale ZRJ-S1 showed denser spatial microstructure and excellent control ability to pore structure of cement-based material. Micropore percentage of more than 200 nm size, which was with serious damage to mechanical performance, was decreased from 17.40 to 11.89%, and porosity of cement-based material itself decreased to 16.20%. As a result, ZRJ-S1 additive showed excellent reinforcement effect on Portland cement.

Measurement of mechanical properties is very important in material science research area. Shear mechanical properties can be obtained from ultrasound vibromery method. Generally, ultrasound vibrometry is based on Voigt model which cannot describe some viscoelastic material accurately. Our method is based on Zener model, and more precise description of mechanical behavior can be measured. In our work, finite element method and experiment are conducted to validate our approach. Shear wave velocities at harmonics in finite element simulation are very close to the theoretical value and the fitting results from experiment demonstrate that our method has better ability to characterize some materials.
