• This paper investigates the stability analysis of plates made of functionally graded material (FGM) and subjected to electro-mechanical loading. A FGM plate with piezoelectric actuator and sensor at top and bottom face is considered. The material properties are assumed to be graded along the thickness direction according to simple power-law distribution in terms of the volume fraction of the constituents, while the poisson，s ratio is assumed to be constant. The plate is simply supported at all edges. Using first order shear deformation theory (FOST), the finite element model is derived with von-Karman hypothesis and as a degenerated shell element. The displacement component of the present model is expanded in Taylor，s series in terms of thickness co-ordinate. The governing equilibrium equation is obtained by using principle of minimum potential energy and solution for critical buckling load is obtained by solving eigenvalue problem. The stability analysis of piezoelectric FG plate is carried out to present th
