Three-dimensional Elasticity Analysis of Rectangular Composite Plates

An analysis of laminated composite plates is performed using the three-dimensional equations of linear elasticity. The methodology of the solution is based on the discrete singular convolution (DSC) method. The governing equations for bending and vibration and related boundary conditions are normalized and discretized via DSC approach. The results are carried out and effects of some parameters on static deformation and free vibration are discussed. The method of DSC provides results that show good agreement with available benchmark problems having different material compositions, thickness, and boundary conditions. It is found that the method of DSC yields accurate and efficient results for the composite laminated plate problems under investigation.
