The objective of this paper is to report preliminary results of a numerical finite element study concerned with the elastic deformation field near the point where a crack front edge intersects the surface of an elastic body. The crack plane as well as the front edge are assumed to be normal to the surface. However, the numerical method, briefly outlined, has a general applicability to three-dimensional elastic singularities involving singular points located on stress singularity lines, such as crack edges, corners, notches, inclusion edges, etc.
