Abstract
ABSTRACTThis article presents closed-form solution for the buckling, postbuckling, and nonlinear deflection of laminated composite plate with two piezoelectric actuators on elastic foundation and under transverse pressure, in-plane compression, thermal, and electrical loads for the first time in the literature. Material properties are assumed to be temperature-dependent. Two cases of boundary conditions and initial imperfection of the plate are considered. The formulations are based on the classical laminated plate theory (CLPT). The Galerkin method is employed to obtain load–deflection relations. The effects of elastic foundation, lateral pressure, in-plane compression, temperature dependency of material properties, electrical and thermal loading, imperfection, and aspect ratio are studied.
