Abstract
This paper is concerned with the theoretical treatment of transient problem of three-dimensional piezothermoelasticity involving a rectangular plate of crystal class mm2 due to partially heat supply in a transient state. We obtain the exact solutions for the three-dimensional temperature change in a transient state and the three-dimensional transient piezothermoelasticity of a simple supported plate. As an example, numerical calculations are carried out for a cadmium selenide solid, and the piezoelectric effects and the effects of the electric surface charge on the displacements, stresses, electric potential, and electric displacements are examined precisely.
