An attempt was made to investigate analytically the mechanical behavio
ur of a semi-infinite piezoelectric medium coated with a perfectly con
ducting thin film under the influence of time-dependent flow of heat a
t the finite end. The problem involves the interaction of three fields
, viz. electrical, mechanical and thermal, and the solution was obtain
ed with the aid of operational calculus. The resultant displacement co
nsists of a time-dependent, as well as a time-independent part and the
variation of displacements exhibits an arc of a parabola.
