A Concise Review on the Interaction Between Stress Waves and Cracks
Abstract
A very important concern on the dynamic fracture of engineering materials is the initiation and propagation of cracks which are subjected to elastic, plastic, or shock waves. However, this review is limited to elastic stress waves for which the theory of elastodynamics is applicable and thereby minimizing the complexity of the report. Several topics were reviewed for this report and, although they were limited to elastic stress waves. The following areas of interest were covered: the development of an experimental method that uses a disc for loading a half-plane crack with a tensile pulse; the response of a crack under plane-strain loading using a plate-impact setup; and, finally, the effects of dilatational (longitudinal) and transverse (shear) waves interacting with a crack.
