✦ Synopsis

In this paper, a single-region BEM formulation for the three-dimensional analysis of fractures in geomechanics is developed. The technique allows the use of continuous elements in the discretization of the crack surfaces. Intially, an example from earthquake control theory is solved to demonstrated the validity of the technique for partially loaded crack surfaces. The method is then extended to deal with contact between crack surfaces by the incorporation of spring constraints. This allows two futher applications to be studied, one from hydraulic fracture and the other involving extraction of an ore seam.

In this paper, a variational technique is described and used to determine the weight functions for three-dimensional dynamic, mixed-mode problems in fracture mechanics. The weight functions required to calculate the stress intensity factors are defined in terms of the derivatives of both traction an
