DISTURBANCES IN A SEMIINFINITE PIEZOELECTRIC MEDIUM COATED WITH A PERFECTLY CONDUCTING THIN-FILM UNDER THE INFLUENCE OF TIME-DEPENDENT FLOWOF HEAT FOR A FINITE INTERVAL

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.
