摘要: Abstract This paper deals with the nonlinear vibration and dynamic response of a shear deformable functionally graded material (FGM) plate surface-bonded piezoelectric fiber reinforced composite actuators (PFRC) in thermal environments. The temperature field considered is assumed to be distributed uniformly over surface varied thickness direction plate, electric transverse component E z only. Material properties substrate FGM layer are according simple power law distribution terms volume fractions constituents, both PFRC layers temperature-dependent. formulations based on higher order deformation theory general von Karman-type equation that includes thermo-piezoelectric effects. numerical illustrations concern characteristics (P/FGM/P) (FGM/P) plates under different sets loading conditions, from which results for monolithic obtained as comparators. reveal effect control voltage natural frequency an larger than actuators. They also show only has small but it significant plate.
