Remarkable progress has recently been made regarding studies of the Boundary Element Method. It has been reported in many papers that BEM offers a powerful means of calculating numerical solutions of engineering problems. Elastic analysis of crack propagation is one of the problems, and in such case BEM is superior in accuracy and economy compared with domain type methods such as the Finite Element Method and the Finite Differential Method. A crack analysis technique using BEM based on formulation of the indirect method is developed, and the effectiveness of the present method is shown for a number of examples of analyses concerning crack problems with arbitrary boundary conditions.
