Dynamic Thermoelastic Problem of a Piezoceramic Plate with a Relaxation Time

Abstract

The present paper deals with the dynamic thermoelastic problem of a thin piezoelectric plate of crystal class 6mm, when not only a relaxation time in the temperature field but also an inertial effect in the elastic field is taken into account. One boundary surface of the thin plate is exposed to a uniform ambient temperature, whereas the other boundary surface is kept at the initial temperature. An exact solution to this problem is obtained by employing the Laplace transform technique. Numerical calculations have been carried out for a thin PZT-5A plate, and the numerical results are illustrated graphically.
