 note = {In this paper, we investigate crack extension behaviors for a linear elastic body with a parallel interacting crack at the neighborhood of the main crack tip. We compute the energy release rate for all the crack tips at the onset of a main crack kinking : E integral is path independent even for a path containing a kinking crack tip and/or the interacting crack tips ; however, for such cases, the well-known J-integral is not path independent. As a result, assuming the isotropy of fracture toughness of the body and judging from the criterion based on the energy release rate, we find that there exist the relative positions of the interacting crack which promote or interrupt the straight extension of the main crack and which make the main crack jump to an extension of an interacting crack.},
