| Abstract: | This paper describes the priority of propagation among three parallel cracks. The treated object is an infinite elastic body with three parallel cracks subjected to uniform tension or antiplane shear at infinity. The results make it clear that the longest crack does not always have the biggest value relating to fracture, e.g. the biggest tangential stress at crack tip or the biggest stress intensity factor, because of the interaction among the cracks. |
