Résumé :
Bending response of corrugated core metallic sandwich panels was studied experimentally under three-point bending loading. Two different core configurations were used: the corrugated monolithic core and the corrugated sliced core. The trapezoidal corrugated cores were manufactured from aluminum sheets via a sheet metal bending mould. After the sandwich panel samples were prepared, they were subjected to three-point bending tests. The load and displacement responses of the sandwich panels having different core configurations were obtained from the experimental testing. The influence of the core configuration on the three-point bending response and failure modes was then investigated. The experimental results revealed that the corrugated sliced core configuration exhibited an improved bending performance compared to the corrugated monolithic core configuration.

Résumé :
The out-of-plane quasi-static compressive behavior of four types of corrugated cores (V-type, U-type, X-type and Y-type core) has been investigated by experiment and FE simulations. By transient dynamic finite element analysis code MSC.Dytran numerical simulations were performed for calculating crushing forces, deformation mode and energy absorption. The FE simulations predict the crush behavior of cores with reasonable accuracy and provide the whole progressive buckling process and deformation modes. Experiment and simulation indicate that the U-type core, V-type core and X-type core structures show excellent crushing resistance performance and energy absorption characteristic. The crush performance of the Y-type core structures is relatively poor because of bending mode.

Résumé :
The paper studied the dynamic response of square aluminum corrugated sandwich panels under projectile impact. The aluminum foam projectile was utilized to apply the impulse on the sandwich panels. In order to increase the applied impulse under controlled impact velocity ( V < 200 m/s), a cylindrical Nylon mass was adhered to the back of foam projectile. Corrugated sandwich panels with two different configurations were tested and their typical deformation modes were obtained in the experiment. Based on the experiment, corresponding numerical simulations were presented. The energy absorption and deformation mechanism of corrugated sandwich panels were studied through the simulation. The influence of impact velocity, thickness of face sheet and wall thickness of corrugated core were discussed. The results indicated that the corrugated sandwich panels with smaller core height produce larger deformation than the panels with larger core height. The face sheets of corrugated sandwich panel absorbed comparable amount of energy with the corrugated core. The velocity histories show that under the combined action of aluminum foam projectile and nylon back mass, a second peak velocity of front face sheet can be produced during the impact process, which is defined as “accelerating impact stage” in current study. The influence of “accelerating impact stage” to the response of structures is sensitive to the impact velocity.

Résumé :
The transverse compression and shear collapse mechanisms of a second order, hierarchical corrugated truss structure have been analyzed. The two competing collapse modes of a first order corrugated truss are elastic buckling or plastic yielding of the truss members. In second order trusses, elastic buckling and yielding of the larger and smaller struts, shear buckling of the larger struts, and wrinkling of the face sheets of the larger struts have been identified as the six competing modes of failure. Analytical expressions for the compressive and shear collapse strengths in each of these modes are derived and used to construct collapse mechanism maps for second order trusses. The maps are useful for selecting the geometries of second order trusses that maximize the collapse strength for a given mass. The optimization reveals that second order trusses made from structural alloys have significantly higher compressive and shear collapse strengths than their equivalent mass first order counterparts for relative densities less than about 5%. A simple sheet metal folding and dip brazing method of fabrication has been used to manufacture a prototype second order truss with a relative density of about 2%. The experimental investigation confirmed the analytical strength predictions of the second order truss, and demonstrate that its strength is about ten times greater than that of a first order truss of the same relative density.

Résumé :
Sandwich structures provide a quite promising solution for blast alleviation techniques owing to their lightweight, high strength, and impressive energy absorption capabilities relative to solo metallic plates with equivalent density. The ability of the sandwich structure to withstand blast loading relies on its core topology. This paper numerically investigates the effectiveness of using ribbon shapes as an innovative core topology for sandwich structures subjected to blast loading. The hydro-code program (Autodyn) supported by the finite element program (ANSYS) is adopted to study the dynamic response of various sandwich panels. The accuracy of the finite element (FE) models were verified using available experimental results for a field blast test in the literature. The results show that the developed finite element model can be reliably exploited to simulate the dynamic behavior of the sandwich panels. The trapezoidal (TZ) and triangular (T) corrugated core topologies were selected to highlight the blast-resistant performance of the new ribbon core topology. Applying the ribbon topology to the traditional corrugated core topologies improved their blast performance. The facing front-plate’s deflection of the trapezoidal corrugated ribbon core sandwich structure (TZRC) has been improved by 45.3% and by 76.5% for the back-plate’s deflection, while for the triangular ribbon corrugated core (TRC), the front plate’s defection has been enhanced by 69.3% and by 112.1% for the back plate. The effect of various design parameters on the blast behavior of the Ribbon-Core Sandwich Panels (RCSPs) was investigated. A parametric study was conducted to evaluate performance indicators, including energy dissipated through plastic deformation and plate deflections. Finally, based on the parametric study, the results of this paper were recommended to be used as a guide for designing metallic ribbon sandwich structures with different protection levels.

Résumé :
In this paper, flatwise tensile test (FWT) and modified double cantilever beam (DCB) experiment were conducted to investigated the debond fracture of sandwich plate with corrugated core. In the experiment, the crack always stays at the face/core interfacial. Tensile bond strength of face core can be given from the flatwise tensile test and we can get the mode I fracture toughness GIC from DCB tests. It is found that the trends of curves change greatly at the beginning, with the propagation of crack, load against open displacement curves change smoothly. In order to simulate the face/core failure of sandwich plate with corrugated core, the cohesive element model is used. Tensile strength and strain energy release rate measured by the experiments presented in this paper are used in as parameters for simulation of the debond fracture. By comparing with the experiment results, the model can express the face/core failure of sandwich plate with corrugated core validly.

Résumé :
Improvement of mechanical properties of light-weight corrugated core sandwich structures is a big demand in aerospace applications. Among these applications, space vehicles which encounter pressure loads and severe aerodynamic heating during ascent and reentry. The open-cell corrugated core is useful for active cooling of the sandwich structures. In this work, hybrid composite structural members with fiberglass corrugated core and carbon fiber skin facings were manufactured using vacuum bag technique. Different specimen configurations with rectangular cross-section area have been subjected to the load in the longitudinal direction of the corrugation and examined by edgewise compression test. The proposed testing has been applied to take advantage of the highest inertia of the specimen in such orientation. The test provides a basis for estimating the load carrying capacity when these structure members are used as individual webs in the aircraft interiors. Also as the core sheet is turned by 90° to the regular load direction, this structure member is similar to the so-called honeycomb when ordered in parallel rows and hence it is appropriate for floor sandwiching. In contrary to a honeycomb, this core consists of fiberglass laminate and therefore higher compressive resistance is associated. The results exhibit high values of both stiffness and ultimate compression force in the corrugation direction. For the rectangular area and the open corrugated contour, specific properties relative to the weight are extremely high. Also, the results and graphs indicate that there must be at least three corrugated ligaments with a trapezoidal cross section of 0.5” height and 63o per cell to grantee stability under load and high absorbed energy in the non-linear stage as well.

Résumé :
In this paper, the dynamic compressive response of metal sinusoidal corrugated core sandwich plates is investigated. The analytical model for the reaction forces of top and bottom face sheets subjected to constant velocity are developed. Finite element (FE) method is carried out to predict the dynamic collapse of metal sinusoidal corrugated cores. Several collapse modes of cores are found in terms of different impact velocity and relative core density. The analytical predications are compared with numerical results, and the analytical model captures numerical results for reaction forces reasonably. The collapse mechanism maps are constructed for sinusoidal corrugated cores with elastic-perfectly plastic material and strain hardening plastic material. The effect of strain rate sensitive on the collapse response is discussed. It is demonstrated that the strain hardening of the metal material increases the dominant deformation mode of the collapse mechanism maps.

Abstract The subject of the analytical and experimental studies therein is of two metal seven-layer beam - plate bands. The first beam - plate band is composed of a lengthwise trapezoidally corrugated main core and two crosswise trapezoidally corrugated cores of faces. The second beam - plate band is composed of a crosswise trapezoidally corrugated main core and two lengthwise trapezoidally corrugated cores of faces. The hypotheses of deformation of a normal to the middle surface of the beams after bending are formulated. Equations of equilibrium are derived based on the theorem of minimum total potential energy. Three-point bending of the simply supported beams is theoretically and experimentally studied. The deflections of the two beams are determined with two methods, compared and presented.

Résumé :
A critical challenge in bridge design and construction process is to reduce the weight of bridge deck. Designers and manufactures tend to put a lot of effort to come up with different solutions for innovative bridge decks. Specifically, in small aged bridges, light modules provide an easy and fast bridge deck renewal. Sandwich panels were introduced as such light weight bridge decks a few decades ago. Steel sandwich panel is composed of three layers of plates; two face sheets and a corrugated core. Low density and high specific strength of the panels provide remarkable advantages for a wide variety of industrial applications. The main objective of this study is to investigate the effect of geometric parameters on the mechanical behavior of the corrugated-core steel sandwich panel. In order to mathematically simulate the panel two mechanical responses of maximum panel deflection and maximum shear force at core and face sheets interface are investigated. A regression model is introduced for each response which obtained from the contributions of the geometric parameters and their interactions. The effect plots revealed that core and face sheet thicknesses highly affect the panel deflection response and weld spacing highly affects the maximum shear force response. Predicted response values obtained from regression model are reasonably close to FEM results. The research also focuses on potential failure scenarios which may occur at the core and face sheets bonding connected via spot weld in the case of over loading. The failure analysis showed that the spot weld detachment in all welding paths starts from the panel edges near the girder supports and propagates toward the center of panel. In addition, as the applied load increases up to 300% of service load, the number of failed welds increases exponentially.

Résumé :
The aim of this research work is to investigate the mechanical properties of corrugated-core sandwich structures under quasi-static and dynamic loading conditions and to determine the failure mechanisms and energy-absorbing characteristics of the corrugated-cores with different cell wall thickness and filled with a foam core. Triangular corrugation structures were made from an aluminium alloy (AL), a glass fibre reinforced plastic (GFRP) and a carbon fibre reinforced plastic (CFRP). The composite corrugations were fabricated using a hot press moulding technique and then adhesively bonded to skins based on the same material, to produce a range of lightweight sandwich structures. The role of the number of unit cells, the thickness of the cell walls and the width in determining the mechanical behaviour of the structures was investigated. Buckling of the struts was identified as the initial failure mode in these corrugated systems. Continued loading resulted in plastic deformation in the aluminium system, in contrast, fibre fracture, matrix cracking and localised delamination in the composite systems, as well as debonding between the skins and the core were observed in the composites. The compression strength and modulus were shown to be dependent on the number of unit cells and the cell wall thickness, but independent of specimen width. Subsequent mechanical testing was undertaken using an Arcan rig capable of generating a range of loading conditions between pure shear and pure compression. The failure strength in the aluminium system was accurately represented using a two dimensional quadratic failure criterion. In contrast, due to the initation of delamination within the composite struts, the composite corrugated-cores were accurately predicted using a modified failure criterion. Low velocity compression loading was subsequently performed on the sandwich structures, where the dynamic strength enhancement factor was shown to increase for all the corrugation systems. This was attributed to both a material strain-rate sensitivity and inertial stabilisation effects. The failure mechanisms in the sandwich structures were found to be similar under both quasi-static and dynamic loading conditions, where damage initiated due to buckling of the struts. To simulate the mechanical response of the corrugation systems, FE models have been developed using the Abaqus finite element package. The FE results were compared to measured responses, and good agreement was achieved. The failure modes predicted by the FE models show reasonably good agreement with the experimental observations. Finally, foam filling the composite corrugation systems significantly improved the specific strength as well as specific energy-absorbing characteristics of the structures. The compression properties of the corrugated structures have been compared to those of other core materials, where the evidence suggests that these systems compare favourably with other cellular core materials.

Résumé :
Metal sandwich panels are becoming increasingly important as multi-functional components in many industrial areas. One of the main characteristics is their high stiffness-to-mass ratio, especially under bending conditions. This property strongly depends on the two faces, but other properties – acoustic, thermal, etc. – are governed by the core. Therefore, R&D in innovative cores is justified by the effort the industry is making to create multi-functional components that integrate good performances in different fields. The multi-functionality of components can be efficiently achieved by using multidisciplinary optimization (MDO) processes. Nevertheless, given their iterative nature, quick but accurate simulations are needed to define component characteristics. In this context, the PhD activity reported in this dissertation aims at developing modelling techniques, even simplified, which allow determining the static and dynamic properties of all-metal corrugated core sandwich panels to include them in optimization processes. To begin with, an analytical formulation to represent a general corrugated core as an equivalent homogeneous layer is presented. The main limitations of already developed formulations are overcome by the proposed methodology. Moreover, given the absence in the literature of accurate formulations for sinusoidal cores, the general one is simplified to adapt it to that specific geometry. Nevertheless, it is shown that, due to manufacturing processes, the real shape of the corrugation is different from the supposed sinusoidal shape. A measurement campaign – tensile testing and modal analysis – is performed to validate the analytical formulation and to prove the importance of modelling the real shape of the corrugation, especially for the modal analysis. Finally, to show the industrial advantages of using the proposed modelling technique, a case study was investigated. An optimization process is set up on sinusoidal corrugated sandwich panels with both static and acoustic constraints applied, which would not be possible without the computational time reduction achieved by the analytical equivalent modelling proposed.

The main objective of this thesis was to study the mechanical characteristics of jute/PLA sandwich composites with a corrugated board as a core layer. The core layer composites were made with corrugated board and polylactic acid. The core layer composites were then stacked with jute fabrics and PLA films on the top and bottom surfaces to fabricate sandwich composites. Two composites (the corrugated board reinforced PLA composites and jute /PLA sandwich composites with the corrugated board as a core layer) were developed in the current study. For the manufacturing of corrugated board reinforced PLA composite core layer, a dipping bath was used to impregnate the corrugated boards with melting solution. For sandwich composites, resin film method and hot press with mold were used to produce the jute /PLA sandwich composites with the corrugated board as a core layer. A material test system (MTS810) was used to study the tensile, compressive, bending properties of the composites. Furthermore, an IZOD impacting instrument was used to examine the impacting characteristics of the composites. Experimental results revealed that both the corrugated board reinforced PLA composites, and jute fabric/PLA sandwich composites have well reinforced efficient. The tensile and compressive modulus of the corrugated board reinforced PLA composites were 144.8% and 6329.7% higher than that of the pure corrugated board, respectively. For the core layer composites, the proper content of the corrugated board was 32%. The tensile and compressive moduli of jute /PLA sandwich composites with the corrugated board as a core layer was 41.5% and 635.3% higher than that of the corrugated board reinforced PLA composites, respectively. The proper content of fiber and board for the sandwich composite was 26%. Both the corrugated board reinforced PLA composites and the jute fabric/PLA sandwich composites with the corrugated board as a core layer reinforcements increase the energy absorption capacity while impacting test.

Résumé :
This thesis focuses on the behavior of a corrugated-core sandwich panel with a concrete top layer under normal loads applied to the concrete face. This sandwich panel is composed of two steel face plates separated by a corrugated sheet welded to them at its crests and troughs. A concrete layer is placed on the top face of the sandwich panel, utilizing shear connectors to ensure composite action. The objective of this study is to examine the structural behavior of these composite panels. This thesis intends to provide design capabilities for applications in which this type of sandwich panel is well suited, e.g., emergency bridge repair, building floors, or fire walls. The panels are analyzed using both elementary beam theory (for narrow panels) and the classical theory of orthotropic plates. In order to complete the theory, the bending stiffnesses in the various directions are determined by structural analysis. To verify the theory, extensive experimental testing has been performed on the sandwich panels. It is found that compression of the core accounts for a majority of the deflection in the relatively thick specimens tested here. Measured deflections are compared with those obtained theoretically, and after corrections are made for core compression, they are in fair agreement.

In this thesis, a validation process is proposed to prove that the Asymptotic Corrugation Boundary Conditions (ACBCs) analysis method can be used for obtaining the electromagnetic field of longitudinally corrugated conical. As a contrast, the numerical field generated by the numerical simulation program is used to compare with the analysis field generated by the ACBCs analysis method. With the favorable similarity between the analysis field and the numerical field, it is shown that the scope of the ACBCs application can be expanded to the spherical coordinate system. The existence of corrugation results in the variation of origin propagation mode. The TE modes of the smooth cone turn into the new propagation mode.

After confirming that the Asymptotic Corrugation Boundary Conditions (ACBCs) can be applied in spherical coordinate system, we begin to discuss the effects of three factors which affect the distribution of electromagnetic fields in the longitudinally corrugated cone. We consider three factors: 1. Frequency. 2. Taper of structure. 3. Width of the groove. After the discussion is completed, we design a kind of size which is easy to measure the distribution of the electromagnetic field to imply. In the end, with the favorable similarity between the simulation results and the measurement results, we can be more certain that the ACBCs can analyze the structure in spherical coordinate system well.

Résumé :
Sandwich structures with corrugated cores have attracted a lot of interest from industrial and academic fields due to their superior crashworthiness. In this paper, the dynamic response of metallic trapezoidal corrugated core sandwich panels under low-velocity impact loading is studied by conducting drop hammer impact testing. The sandwich panels composed of two thin face skins and trapezoidal corrugated core, were designed and fabricated through folding and laser welding technology. Main attention of present study was placed at the influences of the impact energy, impactor diameter and impact location on the impact force, deformation mechanisms and the permanent deflections of the trapezoidal corrugated core sandwich panels. Results revealed that the impact energy has significant effects on the dynamic response of the sandwich panel, whereas the impact diameter has little effects on it. The deformation mode of the front face sheet differs sharply when the impact location is different. The middle unit cell of corrugated core is compressed to the “M” shape under different low-velocity impact loading.

Résumé :
This paper presents a procedure to make composite corrugated core without the need for a mold with corrugated shape. The technique is called 4D printing of composites. The corrugated composite is intended to serve as the core for flexible aircraft wings. A demonstrator sample was manufactured and tested. It was shown that the flexible wing can morph up to 20o and can withstand loads for small unmanned arial vehicles.

Résumé :
The CFD code STAR CD was used to assess the thermal and hydraulic performance of a primary surface type gas turbine recuperator, with Cross Corrugated (CC) surface. The main goal of CFD modeling was to evaluate heat transfer and pressure drops predicted by the 1D methodology and thus to verify the recuperator efficiency. Two computational domains were made. The first for heat transfer and pressure drops simulation in the recuperator core and the latter for pressure drops predicted at the inlet and outlet ports. Details of the recuperator core, computational domains and the boundary conditions for CFD simulation as well as relevant results are presented.

Résumé :
This paper addresses three-dimensional dynamic finite element analysis and validations for strain-rate dependent elastic-plastic sandwich steel plate with various corrugated core arrangements subjected to dynamic air pressure loads. The sandwich steel plate consists of top and bottom flat substrates of Steel 1018 and corrugated core layers of Steel 1008. The developed model is validated with a set of shock tube experiments. Various corrugated core arrangements are taken into consideration for optimizing core design parameters in order to maximize mitigation of blast load effects onto the structure.

Résumé :
Abstract Both linear and weakly nonlinear stability of a core annular flow in a corrugated tube in the limit of thin film and small corrugation are examined. Asymptotic techniques are used to derive the corrugated base flow and corresponding linear and weakly nonlinear stability equations. Interesting features show that the corrugation interaction can excite linear instability, but the nonlinearity still can suppress such instability in the weakly nonlinear regime.
