Abstract

In this research, the critical BUCKLING load of a FGM CIRCULAR PLATE with actuator-actuator PIEZOELECTRIC LAYERs is calculated based on neutral-axis and using higher-order shear deformation plate theory. The plate is clamped and simply supported. Equilibrium and stability equations are derived using the Euler equations, while pre-buckling forces are obtained using the MEMBRANE THEORY. Then, the critical BUCKLING loads are derived and the graphs and tables are presented and compared with other available theoretical data. The results show that for constant thickness of PIEZOELECTRIC LAYER, critical BUCKLING load is increased by increasing the aspect ratio (h/a) and is decreased by increasing volume fraction exponent. Also, for FGM thickness constant, critical BUCKLING load is increased by increasing the aspect ratio (hp/h), while decreased by increasing volume fraction exponent.
