TRANSIENT PIEZOTHERMOELASTICITY OF A HEXAGONAL PLATE OF CLASS 6-MM

Piezoelastic materials entail piezoelectric polarization that is direc tly proportional to the applied strain. Therefore, piezoelastic materi als have recently attracted considerable attention because of their po tential use in intelligent structural systems. In this paper, we treat a transient problem of piezothermoelasticity in a hexagonal plate of class 6 mm subjected to transient temperature change. We analyze the t ransient problem by use of the potential function method, which can se parate the coupling between the thermoelastic and electric fields. Num erical calculations for the transient problem are carried out for a ca dmium selenide solid, and the results are presented graphically in com parison with those for a steady problem.
