Time-domain boundary element method (BEM) for elastodynamic crack analysis is presented in this paper. Special attention is devoted to BEM based on traction boundary integral equations (BIEs) in time-domain. Both the hypersingular and the non-hypersingular traction BIEs are dealt with. A time-steppi...
