Abstract

An analytical study is presented of the influence of inertia effects on the initial stages of debonding at an interface of two elastic solids of different elastic constants and mass densities. The debonding is caused by stress concentrations that are generated when a system of transient horizontally polarized shear waves strikes the tip of an interface flaw. It is shown that for a system of step-stress waves the zone of interface yielding initially extends linearly with time. The speed of the loading edge of the zone of interface yielding and the time of rupture at the trailing edge of the zone of yielding are computed and compared with the corresponding values for the fully dynamic problem.
