Transient response of initially stressed composite sandwich plates

摘要: This paper deals with the transient response of initially stressed composite sandwich plates under time dependent sine, step, triangular and explosive blast loadings. Formulations for a family assumed strain finite element formulations are developed on basis first-order shear deformation theory priori correction factors. The elements contain three displacements two rotations normals about plate's mid-plane. terms in energy formulation integrated exactly using full integration scheme. mass matrix adopted here is consistent nature. Newmark scheme used to integrate governing equations motion. accuracy reliability present verified previously published results literature. New presented examine effects alternative loadings, boundary conditions plate geometries.
