摘要: A theoretical model for geometrically nonlinear vibration analysis of thermo-piezoelectrically actuated circular plates made functionally grade material (FGM) is presented based on Kirchhoff’s–Love hypothesis with von-Karman type geometrical large deformations. The properties the FG core plate are assumed to be graded in thickness direction according power-law distribution terms volume fractions constituents. Dynamic equations and boundary conditions including thermal, elastic piezoelectric couplings formulated solutions derived. An exact series expansion method combined perturbation approach used thermo-electro-mechanical behavior structure. Control plate’s deflections natural frequencies using high control voltages studied their effects evaluated. Numerical results various mixtures ceramic metal dimensionless forms. parametric study also undertaken highlight thermal environment, applied actuator voltage composition characteristics composite
