✦ Synopsis

A new mtegral equation method for the analysls of the interactions between cracks and elastic inclusions embedded in a two-dimensional, linearly elastic, isotropic infinite medium subjected to in-plane force is presented. By distributing dislocations along the crack lines and forces along the matrix-inclusion interfaces, a set ofcoupled integral equations is obtained. The discretization procedure of the integrals involved is discussed and the relations between the stress lntensity factors and the values of the dislocation functions at the respective crack tips are derived. Several sample problems are presented in order to determine the versatility and the accuracy of this approach.
