Abstract
This paper is concerned with the theoretical treatment of transient piezothermoelastic problem is developed for a smart composite hollow cylinder constructed of an isotropic elastic layer and a piezoelectric layer due to uniform heat supply. The transient one-dimensional temperature in a smart composite hollow cylinder is analyzed by the method of Laplace transformation. By using the exact solutions for isotropic hollow cylinder and piezoelectric hollow cylinder, the theoretical analysis of transient piezothermoelasticity is developed for a smart composite hollow cylinder. As an example, numerical calculations are carried out for an isotropic elastic hollow cylinder made of steel, bonded to a piezoelectric layer of cadmium selenide. Some numerical results for the temperature change, the displacement, the stress and the electric potential distributions in a transient state are shown.
