Abstract
In a previous paper an integral equation representation of cracks was presented which differs from the well-known ‘dislocation-layer’ representation. In this new representation, the equations are written in terms of the displacement-discontinuity across the crack surfaces. It was shown that the new technique is well-suited to the treatment of kinked cracks. In the present paper, this integral-equation representation is coupled to the direct boundary-element method for the treatment of finite bodies containing kinked cracks. The resulting approach is shown to be simple, yet very accurate.
