Mechanical Buckling of FG Saturated Porous Rectangular Plate with Piezoelectric Actuators

Abstract

In this study buckling analysis of solid rectangular plate made of porous material bounded with the<br /> layers of piezoelectric actuators in undrained condition is investigated. Porous material properties vary<br /> through the thickness of plate with a specific function. Distributing of the pores through the plate thickness<br /> is assumed to be the nonlinear nonsymmetric distribution. The general mechanical non-linear equilibrium<br /> and linear stability equations are derived using the variational formulations to obtain the governing equations<br /> of piezoelectric porous plate. The effects of piezoelectric layers on critical buckling load of plate, piezoelectric<br /> layer-to-porous plate thickness ratio and actuator voltage are studied. Also, effect of fluid compressibility<br /> and variation of porosity on critical buckling load are investigated in the undrained condition.Closed-form<br /> solutions is used to derive the critical buckling loads of the plate subjected to mechanical loading.The results<br /> obtained for porous plates with the layers of piezoelectric actuators are verified with the known data in<br /> literature.
