The desire to use materials with high strength/weight or stiffness/weight ratio is increased the importance of composite materials nowadays. Due to this, much attention has been devoted to the numerical analysis of composite plates. The performance of well-known numerical methods, Finite Element Method (FEM) and Boundary Element Method (BEM), are based on the quality mesh structures. Meshfree methods are free from the meshes and the drawbacks of mesh-based interpolation techniques. Because of its high convergence rate, Element-Free Galerkin Method (EFGM) is one of the most widely used meshfree method in solid body mechanics and it is a promising candidate for the analysis of composite materials. In this study; deflection analysis of laminated composite plates are studied using EFGM. Several laminated composite plate problems are solved using EFGM and the displacement results of EFGM solutions are compared with the results of exact and FEM solutions at the critical points.
