The scheme is implemented using the displacement discontinuity boundary element framework to represent the regional elastic medium. Special edge elements are described which enable the crack tip opening displacement to be matched to the assumed asymptotic crack tip opening shape as the fracture is propagated. The approach is illustrated using the cases of an incrementally pumped fracture growing in a uniform stress field and in a linearly varying stress field normal to the crack plane, with the crack tip opening shape dominated by a specified Mode I fracture toughness.
