✦ Synopsis

An integral-equation representation of cracks is presented which differs from the well-known "dislocationlayer" representation in that the equations are written in terms of the displacement-discontinuity across the crack surfaces rather than derivatives of the displacement-discontinuity. The advantages of such a representation is that, unlike the dislocation layer, the displacement discontinuity is not singular at crack tips and kinks. The method is demonstrated for two-dimensional infinite domains.
