%X This study investigates the nonlinear dynamic analysis and vibration of shear deformable FGM truncated  conical shell with piezoelectric actuators, resting on Pasternak type elastic foundations in thermal environments by  the analytical approach. Material properties are graded in the thickness direction according to a simple power law  distribution in terms of the fractions of constituents. The governing equations are based on the first-order shear  deformation theory (FSDT) with a von Karman-Donnell-type of kinematic nonlinearity. The Hamilton’s principle is  used to derive the equations of motion of piezoelectric FGM truncated conical shells. Those equations are solved by the Galerkin method and Runge-Kutta method. In numerical results, the effects of applied actuator voltage, temperature, dimensional parameters, semi-vertex angle, material properties and foundations on the nonlinear dynamic response and vibration of the piezoelectric FGM truncated conical shells are discussed in details.
