The paper examines the large deformation flexural response of laminated composites and sandwich plates under various transverse loadings. The mathematical formulation of the actual physical problem of the plate subjected to mechanical loading is presented utilizing different shear deformation theories and von Karman nonlinear kinematics. The nonlinear governing differential equations of equilibrium are linearized using quadratic extrapolation technique. A meshless technique based on radial basis functions (RBFs) is used for analysis of the problems. Laminated and sandwich plates with immovable simply supported and clamped edges and subjected to point, line, sinusoidal and uniformly distributed loads are analyzed. Introduction Plates/panels are one of the important structural elements in aerospace, automotive, marine and other high performance engineering structures. During their service life they are subjected to different loading conditions and resulting deformations may be moderate to large. These structural components are preferably made up of fiber reinforced composites stacked in layers or sandwich constructions resulting in saving of weight. Increase in the industrial use of laminated composites and sandwich construction necessitates the development of effective numerical tools/methods for the analysis of such structures. The large deformation analysis of the laminated composite plates subjected to different types of mechanical loading has been the subject of research interest of many investigators utilizing analytical and numerical tools. Using finite element method, Zhang and Yang [1] and Zhang and Kim [2] presented nonlinear analysis of thin to moderately thick laminated composite plates. Singh and Shukla [3] presented the nonlinear bending response of laminated plates using radial basis function. Transverse bending of shear deformable laminated composite plates in Green– Lagrange sense accounting for the transverse shear and large rotations are presented by Dash and Singh [4]. A semianalytical approach for the geometrically non-linear analysis of rectangular laminated plates with general in-plane and out-of-plane boundary conditions under a general distribution of out-of-plane loads is presented by Shufrin et al [5]. Most popular numerical techniques are based on versatile finite element. Finite difference, differential quadrature and boundary elements methods have also been used. In the last few years, a numerical tool that avoids the problem of mesh generation has gained momentum and has received attention of many researchers primarily due to the flexibility in the construction of finite dimensional sub-spaces. Particularly in case of extremely complex domain of interest, traditional numerical methods are somehow difficult to
