Abstract
Stress fields were found for boundary elements that consist of linear arrays of dislocations, or arrays of dislocations that simulate a crack tip. A number of two-dimensional elastic boundary value problems were solved using these elements. Crack growth paths were predicted for pairs of interacting cracks and the energetics of multiple crack growth away from a free surface was analysed. In certain simple elastic-plastic problems, where the general shape of the plastic zone is known, the plastic zone size was predicted.
