Transient piezothermoelasticity for a cylindrical composite panel composed of cross-ply and piezoelectric laminae

Abstract

This paper is concerned with the theoretical treatment of transient piezothermoelastic problem is developed for a cylindrical composite panel composed of cross-ply laminae and piezoelectric material of crystal class mm2, subject to nonuniform heat supply in the circumferential direction. We obtain the exact solution for the two-dimensional temperature change in a transient state, and transient piezothermoelastic response of a simply supported cylindrical composite panel under the state of plane strain. Some numerical results for temperature change, displacement, stress and electric potential distributions in a transient state are shown in figures. Furthermore, the influence of thickness of the cross-ply laminate on thermal stress or electric field are investigated.
