Abstract
The Kachanov method is modified to analyze 2D crack-crack interactions in b rittle solids under compression. Motivated by the sliding crack mechanism, the interaction of frictional cracks is considered first, followed by the i nteraction of straight winged cracks subject to a pair of concentrated forc es and external compression. The obtained approximate solutions for SIFs ar e compared with the "exact" numerical ones obtained via a boundary element method.
