摘要：
The evolution of stress intensity factors in a mixed loading mode has been calculated for different cleavage planes, the direction of the crack front, and the easy slip systems near the crack tip in a body-centered cubic (bcc) crystal. Calculations take into account the mutual influence of the plastic deformation and crack tip shape as well as T stress. The dependence of screening the crack tip by dislocations on the crack orientation, easy slip system, and fracture modes is found.
