In this work an analytical procedure is developed, to investigate the Transient characteristics of different laminated composite plates based on higher order shear displacement model with zig-zag function. This function improves slope discontinuities at the interfaces of laminated composite plates. The related functions are obtained using the dynamic version of principle of virtual work or Hamilton's principle. The solutions are obtained using Navier's and numerical methods for antisymmetric crossply and angle-ply laminated plates with simply supported boundary conditions. The results are presented for transient analysis subjected to mechanical loading for ant-isymmetric cross-ply and angle-ply laminated plates. All the solutions presented are close agreement with the theory of elasticity and closed form solutions available in the literature.
