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. Copyright © 1999 John Wiley & Sons, Ltd.
