Buckling behavior of rectangular angle-ply laminated composite plates subjected to thermal and mechanical loads using the meshfree method

Abstract

This study aims to explore the buckling behavior of rectangular plate with angle-ply overlay under thermal and mechanical loadings using meshless method. The governing differential equations (GDEs) of the plate are based on a new higher-order shear deformation theory (HSDT) and are discretized using polynomial radial basis function (RBF) to cast a set of equations simultaneously. A code is developed for the solution in MATLAB (2019). Uniform temperature differences and mechanical loads are the cause of in-plane loads. Convergence study has been conducted to check the current formulation’s soundness. The accuracy of the contemporary theory and formulation is validated with the published results. A parametric investigation is conducted for buckling behavior under the span-to-thickness ratio, lamination scheme, effect of the number of layers and effect of length-to-width ratio.
