Abstract This study presents an analysis of the static bending of a sandwich plate composed of a functionally graded (FG) core and face sheets manufactured of piezoelectric material. The sandwich plate is resting on Pasternak's elastic foundations and subjected to sinusoidal thermo-electro-mechanical loads. Four-unknown shear deformation theory is utilized to define the displacement components. The equilibrium equations are established using the virtual work principle and solved by following Navier's solution method. The influences of applied voltage, thermal expansion coefficients, volume fraction exponent, elastic foundations parameters, side to-thickness ratio, and aspect ratio have been discussed. The current formulation is supported by comparisons with the published results.
Highlights The bending of an FG piezoelectric sandwich plate is presented. The plate is subjected to sinusoidal thermo-electro-mechanical loads and resting on Pasternak's foundation. Four-unknown shear deformation theory is employed. The equilibrium equations are established and solved by following Navier’s solution method. The influences of many parameters have been discussed.
