Abstract
This paper is concerned with the numerical treatment of one-spatial dimensional generalized piezothermoelastic wave propagations in piezoelectric plates subjected to thermal, electric, and mechanical loarings. The governing equations are based on the coupled generalized theory of piezothermoelectricity along with the modified Fourier law. The solutions are obtained by the method of characteristics. The numerical calculations are carried out for PZT-4 and nonpiezoelectric plates subjected to impulsive laser-pulse heating.
