Abstract

In this paper, the fictitious stress and displacement discontinuity integral equa- tions are presented in the Laplace transform domain. The two formulations are used to generate an indirect boundary integral equation method for the solution of elastodynamic crack problems. The proposed method is used to evaluate the mixed mode stress intensity factors for several crack configurations subjected to dynamic loading. 1 Introduction The boundary integral equation methods have in recent years proved very successful in solving static crack problems in fracture mechanics; see Aliabadi and Rooke[l] for a review. However, their application to dynamic crack problems is relatively new. The so-called direct boundary integral formulati
