ABSTRACT: The interaction of impact generated elastic stress waves with discontinuities in solids is considered. In this contribution, the evolution in time of damage at a bimaterial interface is described by an exponential growth law of Kachanov-type and a finite difference method has been adapted for the investigation of progressive deterioration of an interface. The particular case of a shear wave impacted stick-slip-interface is presented.
