摘要

The influence of a thermally mismatched inclusion on the stress intensity factors at the tips of an interacting crack is investigated. The analytical expressions for the stress intensity factors K-I and K-II of a crack submitted to the stresses due to the thermal misfit of a constrained inclusion are given by using an appropriate dislocation density function. The stress intensity factors vary with the size, position and the thermal misfit strain of the inclusion. The characteristics of this crack-inclusion interaction problem are analyzed and discussed.
