Abstract :
The eigenfunction expansion method in dynamic electroelasticity suggested earlier by the author, is applied to problems of electric discharge of piezoelectric bodies. Three problems are considered: (i) discharge of a piezoceramic rod, electrically loaded by a static potential difference; (ii) single discharge of the rod excited by harmonic mechanical loadings and (iii) periodic sequence of discharges under harmonic mechanical excitation
