Abstract: “Piezolaminated smart structures are mostly used as light weight structures to control structural response in various structural applications. Piezoelectric materials possesses a property of direct and converse piezoelectric effects which can be adequately employed to control the deflection, vibration, shape and buckling of the structure. Due to the application of piezoelectric materials to control structural response, stability and control of light weight structures tends to be the governing criterion which requires significant attention. A finite element methodology is developed for stability analysis of smart piezolaminated composite plates subjected to combined action of electrical and mechanical loading. The finite element formulation is based on higher order shear deformation theory. Numerical analysis is made for stability analysis of simply supported piezolaminated plate”
