Abstract

An improved technique for solving crack-microcrack interaction problems is developed, based on the Green's function for a dislocation dipole placed in the vicinity of a main crack. The microcrack array is characterized by the microcrack density, orientation and length distributions. The stress field near the main crack tip is taken as a sum of a singular term of an anisotropic problem with stress intensity factor K, and a regular term. K and the regular term are determined from a system of equations obtained by self-consistency arguments. The proposed technique is illustrated by numerical solutions of several interaction problems for particular configurations of microcrack array.
