exact solution for rectangular sandwich plate with embedded piezoelectric shear actuator

This paper presentsan exact solutionwhich is obtainedby extending the state space formulation.this solution will be compared with finite element modeling technique. The study uses ABAQUS andANSYS softwares to derive the finITE element model of the rectangular sandwich plate the presented exactsolution is obtained for the three dimensional deformations of simply supported laminated rectangular thick plates with embedded shear mode piezoelectric actuators subjected to mechanical and electrical loading on the upper and lower surfaces. each layer of the laminate is made of either an orthotropic elastic material or a piezoelectric material whose poling vector direction lies in the plane of the plate with perfect bonding between the adjoining layers.
