Frictional slip and separation in the transonic range caused by a plane stress pulse

Abstract

Localized frictional slip and separation slip between two contacting solids caused by an incident plane elastic wave of arbitrary form was studied in reference [1]. In that paper the angle of incidence of the wave was restricted to produce a disturbance propagating along the interface with supersonic speed. The results were obtained in closed form and conventent graphical representations were given. Here the investigation is continued in the transonic range by using a dislocation formulation that leads to singular integral equations. Examples of localized slip, separation-slip and slip-separation-slip are given for identical materials. Some of the results are in closed form, while other results are obtained by numerical integration.
