Abstract
An analysis of the diffraction of horizontally polarized shear waves of arbitrary profile by a finite crack extending uniformly is investigated. Transform techniques and a generalized Wiener-Hopf method are employed to solve the mixed boundary-value problem exactly from the instant the incident wave first strikes the crack until the diffracted wave reaches the opposite edge, is rediffracted, and then returns the original edge. The dynamic stress-intensity factors for an incident wave with a step function stress profile are obtained as functions of time, the angle of incidence and the speed of crack propagation. The effects of the aforementioned system parameters on the dynamic stress-intensity factors are shown graphically.
