Buckling analysis of three-layered rectangular plate with piezoelectric layers

This paper employs an analytical method to analyze the buckling of piezoelectric coupled plates with different boundary conditions on the basis of the first order shear deformation plate theory. The structure is composed of a host isotropic plate and two bonded piezoelectric layers. Convergence study is performed in order to verify the numerical stability of the presented method. Also, the present analysis is validated by comparing the results with those in the literature, and then the critical buckling load of the piezoelectric coupled plates is presented in tabular and graphical forms for different plate aspect ratios, thickness of the piezoelectric, actuator voltage and boundary conditions.
