borders of cracks. The solution is employed to determine stress components in the cracked domain under the anti plane deformation. The plastic region around the tips of a crack is specified using von Mises yield criterion. The analysis allows consideration of both singular and non-singular terms of stress fields. We observed that the interaction between cracks has crucial effect on the shape and size of the plastic region. Also for interacting cracks, using von Mises yield criterion is a better way to specify the plastic zone size in comparison with the simple Irwin's model. References Chen, Y.Z., 1991.
