Abstract
In this study, the theoretical analysis of three-dimensional transient piezothermoelasticity is developed for a rectangular composite plate composed of cross-ply laminae and piezoelectric material of crystal class mm2, subject to partial heat supply. We obtain the exact solutions for the three-dimensional temperature change in a transient state, and three-dimensional transient piezothermoelasticity of a simply supported combined plate. As an example, numerical calculations are carried out for a cross-ply laminated rectangular plate made of alumina fiber-reinforced aluminum composite, associated with a piezoelectric plate of a cadmium selenide solid. Some numerical results for temperature change, displacement, stress, electric potential, and electric displacement distributions in a transient state are shown in figures. Furthermore, the influence of thickness of the piezoelectric plate on thermal stress or electric field are investigated.
