The quadrilateral plate elements include the 4-node conforming plate element based on the classical laminate plate theory (CLPT), the 4-node and 9-node Mindlin plate element based on the first-order shear deformation laminated plate theory (FSDT), and a displacement-based 4-node quadrilateral element (RDKQ-NL20). Using the von-Karman’s large deflection theory and the total Lagrangian (TL) approach, the nonlinear FE governing equations for plate under thermal load are derived. Convergence analysis for four elements is first conducted. These elements are then used to predict the stable shapes of thermally-induced bistable plate. Numerical test shows that the plate element based on FSDT, namely the 4-node and 9-node Mindlin, and the RDKQ-NL20 plate element can predict two stable cylindrical shapes while the 4-node conforming plate predicts a saddles shape. Comparing the simulation results with ABAQUS, the RDKQ-NL20 element shows the best accuracy among all the elements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bistable" title="Bistable">Bistable</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=geometrical%20nonlinearity" title=" geometrical nonlinearity"> geometrical nonlinearity</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrilateral%20plate%20elements" title=" quadrilateral plate elements"> quadrilateral plate elements</a> </p> <a href="https://publications.waset.org/abstracts/124454/finite-element-analysis-of-thermally-induced-bistable-plate-using-four-plate-elements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124454.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6455</span> Composite Laminate and Thin-Walled Beam Correlations for Aircraft Wing Box Design </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20J.%20M.%20Mohd%20Saleh">S.

At present, the option for composite usage in aircraft component is largely based on experience, knowledge, benchmarking and partly market driven. An inevitable iterative design during the design stage and validation process will increase the development time and cost. This paper aims at presenting the correlation between laminate and composite thin-wall beam structure, which contains the theoretical and numerical investigations on stiffness estimation of composite aerostructures with applications to aircraft wings. Classical laminate theory and thin-walled beam theory were applied to define the correlation between 1-dimensional composite laminate and 2-dimensional composite beam structure, respectively. Then FE model was created to represent the 3-dimensional structure. A detailed study on stiffness matrix of composite laminates has been carried out to understand the effects of stacking sequence on the coupling between extension, shear, bending and torsional deformation of wing box structures for 1-dimensional, 2-dimensional and 3-dimensional structures. Relationships amongst composite laminates and composite wing box structures of the same material have been developed in this study. These correlations will be guidelines for the design engineers to predict the stiffness of the wing box structure during the material selection process and laminate design stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircraft%20design" title="aircraft design">aircraft design</a>, <a href="https://publications.waset.org/abstracts/search?q=aircraft%20structures" title=" aircraft structures"> aircraft structures</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20lamination%20theory" title=" classical lamination theory"> classical lamination theory</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20structures" title=" composite structures"> composite structures</a>, <a href="https://publications.waset.org/abstracts/search?q=laminate%20theory" title=" laminate theory"> laminate theory</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20design" title=" structural design"> structural design</a>, <a href="https://publications.waset.org/abstracts/search?q=thin-walled%20beam%20theory" title=" thin-walled beam theory"> thin-walled beam theory</a>, <a href="https://publications.waset.org/abstracts/search?q=wing%20box%20design" title=" wing box design "> wing box design </a> </p> <a href="https://publications.waset.org/abstracts/80552/composite-laminate-and-thin-walled-beam-correlations-for-aircraft-wing-box-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80552.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">232</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6454</span> Behavior of Laminated Plates under Mechanical Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoudi%20Noureddine">Mahmoudi Noureddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study the use of two variable refined plate theories of laminated composite plates to static response of laminated plates.

The behaviour of a layer is ex-pressed through elasticity coupled to damage. The elastic strain is due to the elasticity of the layer and can be modeled by using the classical laminate theory, and the laminate is considered as an orthotropic material. This means that no coupling effect between strain and curvature is considered. In the present work, the damage is associated to cracking of the matrix and parallel to the fibers and it being taken into account by the changes in the stiffness of the layers. The anisotropic damage is completely described by a single scalar variable and its evolution law is specified from the principle of maximum dissipation. The stress/strain relationship is investigated in plane stress loading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage" title="damage">damage</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior%20modeling" title=" behavior modeling"> behavior modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=meso-macro%20model" title=" meso-macro model"> meso-macro model</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20laminate" title=" composite laminate"> composite laminate</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20loading" title=" membrane loading"> membrane loading</a> </p> <a href="https://publications.waset.org/abstracts/15570/a-meso-macro-model-prediction-of-laminated-composite-damage-elastic-behaviour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15570.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">476</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6451</span> The Theory of Relativity (K)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igor%20Vladimirovich%20Kuzminov">Igor Vladimirovich Kuzminov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The proposed article is an alternative version of the Theory of Relativity.

The studies conducted have permitted the development of a simple design expression to determine the critical shear buckling stress in aluminum web panels. This expression takes into account the effects of reduction of strength in aluminum alloys due to the welding process. Ultimate shear resistance (USR) of plate girders can be obtained theoretically using Cardiff theory or Hӧglund’s theory. USR of aluminum alloy plate girders predicted theoretically using BS8118 appear inconsistent when compared with test data. Theoretical predictions based on Hӧglund’s theory, are more realistic. Cardiff theory proposed to predict the USR of steel plate girders only. Welded aluminum alloy plate girders studied experimentally by others; the USR resulted from tests are reviewed. Comparison between the test results with the values obtained from Hӧglund’s theory, BS8118 design method, and Cardiff theory performed theoretically. Finally, a new equation based on Cardiff tension-field theory proposed to predict theoretically the USR of aluminum plate girders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20resistance" title="shear resistance">shear resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum" title=" aluminum"> aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=Cardiff%20theory" title=" Cardiff theory"> Cardiff theory</a>, <a href="https://publications.waset.org/abstracts/search?q=H%D3%A7glund%27s%20theory" title=" Hӧglund's theory"> Hӧglund's theory</a>, <a href="https://publications.waset.org/abstracts/search?q=plate%20girder" title=" plate girder"> plate girder</a> </p> <a href="https://publications.waset.org/abstracts/2896/a-new-developed-formula-to-determine-the-shear-buckling-stress-in-welded-aluminum-plate-girders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2896.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">426</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6449</span> Free Vibration Characteristics of Nanoplates with Various Edge Supports Incorporating Surface Free Energy Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeid%20Sahmani">Saeid Sahmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to size-dependent behavior of nanostrustures, the classical continuum models are not applicable for the analyses at this submicrion size. Surface stress effect is one of the most important matters which make the nanoscale structures to have different properties compared to the conventional structures due to high surface to volume ratio. In the present study, free vibration characteristics of nanoplates are investigated including surface stress effects. To this end, non-classical plate model based on Gurtin-Murdoch elasticity theory is proposed to evaluate the surface stress effects on the vibrational behavior of nanoplates subjected to different boundary conditions. Generalized differential quadrature (GDQ) method is employed to discretize the governing non-classical differential equations along with various edge supports. Selected numerical results are given to demonstrate the distinction between the behavior of nanoplates predicted by the classical and present non-classical plate models that leads to illustrate the great influence of surface stress effect. It is observed that this influence quite depends on the magnitude of the surface elastic constants which are relevant to the selected material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanomechanics" title="nanomechanics">nanomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20stress" title=" surface stress"> surface stress</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title=" free vibration"> free vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=GDQ%20method" title=" GDQ method"> GDQ method</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20scale%20effect" title=" small scale effect"> small scale effect</a> </p> <a href="https://publications.waset.org/abstracts/41928/free-vibration-characteristics-of-nanoplates-with-various-edge-supports-incorporating-surface-free-energy-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41928.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">356</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6448</span> Ultimate Shear Resistance of Plate Girders Part 2- Höglund Theory </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20S.%20Elamary">Ahmed S.

This paper will be concerned with predicting the USR using Hӧglund theory and EC3. Two main factors can affect the USR, the panel width “b” and the web depth “d”, consequently, the panel aspect ratio (b/d) has to be identified by limits. In most of the previous study, there is no limit for panel aspect ratio indicated. In this paper theoretical analysis has been conducted to study the effect of (b/d) on the USR. The analysis based on ninety-six test results of steel plate girders subjected to shear executed and collected by others. New formula proposed to predict the percentage of the distance between the plastic hinges form in the flanges “c” to panel width “b”. Conservative limits of (c/b) have been suggested to get a consistent value of USR. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultimate%20shear%20resistance" title="ultimate shear resistance">ultimate shear resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=plate%20girder" title=" plate girder"> plate girder</a>, <a href="https://publications.waset.org/abstracts/search?q=H%D3%A7glund%E2%80%99s%20theory" title=" Hӧglund’s theory"> Hӧglund’s theory</a>, <a href="https://publications.waset.org/abstracts/search?q=EC3" title=" EC3"> EC3</a> </p> <a href="https://publications.waset.org/abstracts/2897/ultimate-shear-resistance-of-plate-girders-part-2-hoglund-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2897.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">412</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6447</span> Proportionally Damped Finite Element State-Space Model of Composite Laminated Plate with Localized Interface Degeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shi%20Qi%20Koo">Shi Qi Koo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Beng%20Hong%20Kueh"> Ahmad Beng Hong Kueh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work, the finite element formulation for the investigation of the effects of a localized interfacial degeneration on the dynamic behavior of the [90˚/0˚] laminated composite plate employing the state-space technique is performed.

This includes an introduction of an interface layer adopting the virtually zero-thickness formulation to model the interfacial degeneration. Also, the kinematically consistent mass matrix and proportional damping have been formulated to complete the free vibration governing expression. To simulate the interfacial degeneration of the laminate, the degenerated areas are defined from the center propagating outwards in a localized manner. It is found that the natural frequency, damped frequency and damping ratio of the plate decreases as the degenerated area of the interface increases.

One way to achieve this objective is through the replacement of metallic structures with composites. The main advantages of composite materials are to be lightweight and to offer high specific strength and stiffness. Composite materials can be classified in various ways based on the fiber types and fiber orientations. Fiber reinforced composite laminates are prepared by stacking single sheet of continuous fibers impregnated with resin in different orientation to get the desired strength and stiffness. This research aims to understand the effects of Lamina Stacking Sequence (LSS) on the structural response of a symmetric composite laminate, defined by [0/60/-60]s. The Lamina Stacking Sequence (LSS) represents how the layers are stacked together in a composite laminate. The [0/60/-60]s laminate represents a composite plate consists of 6 layers of fibers, which are stacked at 0, 60, -60, -60, 60 and 0 degree orientations. This laminate is also called symmetric (defined by subscript s) as it consists of same material and having identical fiber orientations above and below the mid-plane. Therefore, the [0/60/-60]s, [0/-60/60]s, [60/-60/0]s, [-60/60/0]s, [60/0/-60]s, and [-60/0/60]s represent the same laminate but with different LSS. In this research, the effects of LSS on laminate in-plane and bending moduli was investigated first. The laminate moduli dictate the in-plane and bending deformations upon loading. This research also provided all the setup and techniques for measuring the in-plane and bending moduli, as well as how the stress distribution was assessed. Then, the laminate was subjected to in-plane force load and bending moment. The strain and stress distribution at each ply for different LSS was investigated using the concepts of Macro-Mechanics. Finally, several numerical simulations were conducted using the Finite Element Analysis (FEA) software ANSYS to investigate the effects of LSS on deformations and stress distribution. The FEA results were also compared to the Macro-Mechanics solutions obtained by MATLAB. The outcome of this research helps composite users to determine the optimum LSS requires to minimize the overall deformation and stresses. It would be beneficial to predict the structural response of composite laminates analytically and/or numerically before in-house fabrication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite" title="composite">composite</a>, <a href="https://publications.waset.org/abstracts/search?q=lamina" title=" lamina"> lamina</a>, <a href="https://publications.waset.org/abstracts/search?q=laminate" title=" laminate"> laminate</a>, <a href="https://publications.waset.org/abstracts/search?q=lamina%20stacking%20sequence" title=" lamina stacking sequence"> lamina stacking sequence</a>, <a href="https://publications.waset.org/abstracts/search?q=laminate%20moduli" title=" laminate moduli"> laminate moduli</a>, <a href="https://publications.waset.org/abstracts/search?q=laminate%20strength" title=" laminate strength"> laminate strength</a> </p> <a href="https://publications.waset.org/abstracts/193315/understanding-the-effects-of-lamina-stacking-sequence-on-structural-response-of-composite-laminates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193315.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">10</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6445</span> New Techniques to Decrease the Interfacial Stress in Steel Beams Strengthened With FRP Laminates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20S.%20Bouchikhi">A.

It is known that the decrease of FRP plate thickness and the fitness of adhesive reduce the stress concentration at plate ends. Another way is to use a plate with a non uniform section or tapered ends and softer adhesive at the edges. In this paper, a comprehensive finite element (FE) study has been conducted to investigate the effect of mixed adhesive joints (MAJ) and tapering plate on the inter facial stress distribution in the adhesive layer, this paper presents the results of a study of application of two adhesives with different stiffnesses (bi-adhesive) along the joint strength length between the CFRP-strengthened steel beam for tapered and untapered plate on the distribution of inter facial stresses. A stiff adhesive was applied in the middle portion of the joint strength, while a low modulus adhesive was applied towards the edges prone to stress concentrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FRP" title="FRP">FRP</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20adhesive%20joints" title=" mixed adhesive joints"> mixed adhesive joints</a>, <a href="https://publications.waset.org/abstracts/search?q=stresses" title=" stresses"> stresses</a>, <a href="https://publications.waset.org/abstracts/search?q=tapered%20plate" title=" tapered plate"> tapered plate</a>, <a href="https://publications.waset.org/abstracts/search?q=retrofitted%20beams%20bonded" title=" retrofitted beams bonded"> retrofitted beams bonded</a> </p> <a href="https://publications.waset.org/abstracts/19553/new-techniques-to-decrease-the-interfacial-stress-in-steel-beams-strengthened-with-frp-laminates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19553.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">498</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6444</span> Parameters Optimization of the Laminated Composite Plate for Sound Transmission Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu%20T.%20Tsai">Yu T.

A thin rectangular plate of variable thickness that is simply-supported on all sides is used as an analytical model of the research. This model is used to study the response of the guitar soundboard as the latter can be considered as a modified form of a rectangular plate. Homotopy Perturbation Method (HPM) is selected as a mathematical method to obtain an analytical solution of the 4th-order parabolic partial differential equation of motion of the rectangular plate of constant thickness viewed as a linear problem. This procedure is generalized to the nonlinear problem of the rectangular plate with variable thickness and an analytical solution can also be obtained. Sound power is used as a parameter to investigate the acoustic radiation of soundboards made from spruce using various bracing patterns. The sound power of soundboards made from Malaysian softwood such as damar minyak, sempilor or podo are investigated to determine the viability of replacing spruce as future materials for soundboards of Classical guitars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rectangular%20plates" title="rectangular plates">rectangular plates</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title=" analytical solution"> analytical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=homotopy%20perturbation" title=" homotopy perturbation"> homotopy perturbation</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequencies" title=" natural frequencies"> natural frequencies</a> </p> <a href="https://publications.waset.org/abstracts/79531/vibration-response-of-soundboards-of-classical-guitars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79531.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">389</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6441</span> Application of the Extended Kantorovich Method to Size-Dependent Vibrational Analysis of Fully Clamped Rectangular Micro-Plates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20R.%20Askari">Amir R.

To this end, a size-dependent Kirchhoff plate model is considered and the equation of motion which accounts for the effect of residual and couple stress components is derived using the Hamilton's principle. The eigenvalue problem associated with the free vibrations of fully clamped micro-plates is extracted and solved analytically using the extended Kantorovich method (EKM). The present findings are compared and validated by available results in the literature and an excellent agreement between them is observed. A parametric study is also conducted to show the significant effects of couple stress components on natural frequencies of fully clamped micro-plates. It is found that the ratio of MCST natural frequencies to those obtained by the classical theory (CT) only depends on the Poisson's ratio of the plate and is totally independent of plate's aspect ratio for cases with no residual stresses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vibrational%20analysis" title="vibrational analysis">vibrational analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20couple%20stress%20theory" title=" modified couple stress theory"> modified couple stress theory</a>, <a href="https://publications.waset.org/abstracts/search?q=fully%20clamped%20rectangular%20micro-plates" title=" fully clamped rectangular micro-plates"> fully clamped rectangular micro-plates</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20Kantorovich%20method." title=" extended Kantorovich method.

The theoretical model is based on the classical plate theory and the Von Kármán geometrical non-linearity assumptions.

The interest in bi-stable structures comes from their ability that these structures can have two different stable equilibrium configurations to define a discrete set of stable shapes. The structures can easily change the first stable shape to the second one by a simple snap action. The main purpose of the current research is to consider the effect of including resin layers on the stability characteristics of bi-stable laminates. To this end and In order to determine the magnitude of the loads that are responsible for snap through and snap back phenomena between two stable shapes of the laminate, a non-linear finite element method (FEM) is utilized. An experimental investigation was also carried out to study the critical loads that caused snapping between two different stable shapes. Several specimens were manufactured from T300/5208 graphite-epoxy with [0/90]T, [-30/60]T, [-20/70]T asymmetric stacking sequence. In order to create an accurate finite element model, different thickness of resin layers created during the manufacturing process of the laminate was measured and taken into account. The geometry of each lamina and the resin layers was characterized by optical microscopy from different locations of the laminates thickness. The exact thickness of each lamina and the resin layer in all specimens with [0/90]T,[-30/60]T, [-20/70]T stacking sequence were determined by using image processing technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bi-stable%20laminates" title="bi-stable laminates">bi-stable laminates</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=graphite-epoxy%20plate" title=" graphite-epoxy plate"> graphite-epoxy plate</a>, <a href="https://publications.waset.org/abstracts/search?q=snap%20behavior" title=" snap behavior"> snap behavior</a> </p> <a href="https://publications.waset.org/abstracts/66025/stability-characteristics-of-angle-ply-bi-stable-laminates-by-considering-the-effect-of-resin-layers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66025.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6435</span> Thermal Elastic Stress Analysis of Steel Fiber Reinforced Aluminum Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Re%C5%9Fit%20Habo%C4%9Flu">Mustafa Reşit Haboğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kur%C5%9Fun"> Ali Kurşun </a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eafak%20Aksoy"> Şafak Aksoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Halil%20Aykul"> Halil Aykul</a>, <a href="https://publications.waset.org/abstracts/search?q=Numan%20Behl%C3%BCl%20Bekta%C5%9F"> Numan Behlül Bektaş</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A thermal elastic stress analysis of steel fiber reinforced aluminum laminated composite plate is investigated.

The dynamic analysis in the present work covered parametric studies on a composite laminated plate (square plate) to determine its effect on the natural frequency of the plate. The parametric study is represented by set of changes (plate thickness, number of layers, support conditions, layer orientation), and the plates have been simulated by using ANSYS package 12. The boundary conditions considered in this study, at all four edges of the plate, are simply supported and fixed boundary condition. The results obtained from ANSYS program show that the natural frequency for both fixed and simply supported increases with increasing the number of layers, but this increase in the natural frequency for the first five modes will be neglected after 10 layers. And it is observed that the natural frequency of a composite laminated plate will change with the change of ply orientation, the natural frequency increases and it will be at maximum with angle 45 of ply for simply supported laminated plate, and maximum natural frequency will be with cross-ply (0/90) for fixed laminated composite plate. It is also observed that the natural frequency increase is approximately doubled when the thickness is doubled. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laminated%20plate" title="laminated plate">laminated plate</a>, <a href="https://publications.waset.org/abstracts/search?q=orthotropic%20plate" title=" orthotropic plate"> orthotropic plate</a>, <a href="https://publications.waset.org/abstracts/search?q=square%20plate" title=" square plate"> square plate</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency%20%28free%20vibration%29" title=" natural frequency (free vibration)"> natural frequency (free vibration)</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20%28graphite%20%2F%20epoxy%29" title=" composite (graphite / epoxy)"> composite (graphite / epoxy)</a> </p> <a href="https://publications.waset.org/abstracts/63332/parametric-study-on-dynamic-analysis-of-composite-laminated-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63332.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">348</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6431</span> Efficiency of the Strain Based Approach Formulation for Plate Bending Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamal%20Hamadi">Djamal Hamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sifeddine%20Abderrahmani"> Sifeddine Abderrahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Toufik%20Maalem"> Toufik Maalem</a>, <a href="https://publications.waset.org/abstracts/search?q=Oussama%20Temami"> Oussama Temami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years many finite elements have been developed for plate bending analysis. The formulated elements are based on the strain based approach. This approach leads to the representation of the displacements by higher order polynomial terms without the need for the introduction of additional internal and unnecessary degrees of freedom. Good convergence can also be obtained when the results are compared with those obtained from the corresponding displacement based elements, having the same total number of degrees of freedom. Furthermore, the plate bending elements are free from any shear locking since they converge to the Kirchhoff solution for thin plates contrarily for the corresponding displacement based elements. In this paper the efficiency of the strain based approach compared to well known displacement formulation is presented. The results obtained by a new formulated plate bending element based on the strain approach and Kirchhoff theory are compared with some others elements.

The analysis of laminated composite plates in three-dimensional (3D) elasticity is a complex problem, as it requires accounting for the orthotropic anisotropic nature of the material and the interactions between multiple layers. Conventional approaches, such as the classical plate theory, provide simplified solutions but are limited in performing exact analysis of the plate. To address such a challenge, the state space method emerges as a powerful numerical technique for modeling the behavior of laminated composites in 3D. The state-space method involves transforming the governing equations of elasticity into a state-space representation, enabling the analysis of complex structural systems in a systematic manner. Here, an effort is made to perform a 3D elasticity analysis of plates with cross-ply and angle-ply laminates using the state space approach. The state space approach is used in this study as it is a mixed formulation technique that gives the displacements and stresses simultaneously with the same level of accuracy. <p
