Disturbances in a Semi-Infinite Piezoelectric Medium Coated with a Perfectly Conducting Thin Film under the Influence of Time-Dependent Flow of Heat for a Finite Interval

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