In this study, we deal with a three-dimensional transient piezothermoelasticity problem of a functionally graded rectangular plate associated with a piezoelectric plate due to partially heat supply. Assuming the functionally graded rectangular plate has nonhomogeneous thermal and mechanical material properties in the thickness direction, the three-dimensional temperature in a transient state and three-dimensional transient thermal stresses of a simple supported plate for functionally graded material are analyzed by introducing the theory of laminated composites as one of theoretical approximation. We investigate the influence of nonhomogeneous thermal and mechanical material properties on the displacement, the stress, electric potential, and electric displacement distribution.
