In this work an analytical solution based on higher order shear deformation theory has been developed. In the Higher Order Shear Deformation Theory, the displacement model is considered in account for non linear variation of in plane and transverse displacements through the plate thickness. The major objective of present study is to determine the transient characteristics of piezoelectric laminated plates with different lamination schemes, geometrical parameters, loads, degree of orthotropy and boundary conditions by two higher order models. The derivation of equation of motion and solutions of higher order model are obtained by using the principle of virtual work and Navier’s method. The Newmark’s time integration scheme is used for finding transient characteristics. The numerical results are computed and tabulated in non dimensional form for various boundary conditions, stacking sequences, aspect ratios, degree of orthotropy and loads. The effects of shear deformation, coupling and degree of orthotropy on transient response of laminated composite plates are investigated. Key words: Piezoelectric Laminated Composite Plates, Higher Order Shear Deformation Theory, Principle of Virtual Work, Newmark’s Time Integration Method. Cite this Article: P.
