Dynamic Finite Difference Analysis of an Axially Cracked Pressurized Pipe Undergoing Large Deformations

Source

An axial through crack was suddenly introduced into the wall of a pipe which was pressurized by either hot water or air. The crack tip was assumed to advance along the pipe according to a fracture criterion based upon the character of the deformation. For brittle elastic failure a maximum stress intensity factor was utilized, while for a plastic stress field, a maximum strain criterion was used. The fluid pressure in the pipe was calculated by a finite difference method in which the effect of the outflow through the crack was taken into consideration.
