ABSTRACT
The present study is the investigation of transient characteristics for the piezoelectric laminated
composite plates subjected to electro-mechanical loading. 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,
