An accurate method for solving crack problems with discontinuous crack-line tractions

A numerical method for the integration of the singular integral equation resulting from a surface crack with discontinuous tractions is presented. The crack is modelled as a pile-up of dislocations, and the dislocation density function is partitioned into three terms: A singular term due to the trac...
