Boundary Element Methods for Two Dimensional Bimaterial Fracture Problems
The work described below examines the application of boundary element techniques to problems in which the bond between two regions occupied by dissimilar elastic materials is weakened by cracks.
The numerical method employed is a modification of the displacement discontinuity method and the explicit forms of the influence coefficients for a quadratically varying discontinuity across a bimaterial interface are given.
Results are obtained for an example problem and are compared with the known analytic solution.
