Abstract

By applying the new boundary integral formulation for two-dimensional elastic bodies containing cracks and holes proposed recently by Chau and Wang (1996), an effective boundary element method for calculating the interaction between cracks and holes is presented in this paper. In the crack tips, singular interpolation functions of order /"* are introduced to model crack tip singularity. The singular boundary integrals involved at the element level are integrated analytically. For each of the hole boundaries, an additional unknown constant is introduced such that displacement compatibility condition can be satisfied exactly by the
