A DQ large deformation analysis of composite plates on nonlinear elastic foundations

摘要: Abstract In this paper an attempt is made to explore the applicability and accuracy of a recently developed differential quadrature (DQ) methodology, for nonlinear analysis composite plates. For purpose, large deformation analyses symmetric antisymmetric cross ply, thin, elastic rectangular laminated plates rested on foundations are investigated. Thin plate theory in conjunction with Green’s strain von Karman assumptions used modeling behavior The governing equations discretized at whole domain grid points boundary conditions implemented exactly points. DQ solutions based first-order shear (FSDT) also obtained comparative studies between two approaches different cases. Convergence methodology demonstrated results compared existing other methods. It shown that accurate even when using only small number
