Summary
Much attention is paid to the responses of solid materials with crack-like defects to impact loading. Chen and Sih [1,6] investigated the transient response of a crack to impact load, solved the problem in the Laplace transform domain, and performed inverse Laplace transform numerically to get the time history of the dynamic stress intensity factors. This paper presented a boundary integral equation method (BIEM) in the frequency domain for transient dynamic crack analysis in isotropic and linear elastic solids subjected to impact loading. Under deformation of the elastic material, the initial contact area will change in time, and the shape of the contact area would be unknown beforehand and must be determined as a part of the solution Considering this crack face interaction effect for the case of transient impact loading will be the natural stage of the research
