Based upon photographs of running cracks, a simple split ring model is proposed to simulate axially running cracks in very ductile materials. The model is used in conjunction with a one-dimensional transient fluid flow analysis to calculate the velocity of the crack and the fluid pressure history for air, cold water, and hot water-filled pipes. The model is capable of predicting crack initiation, extension, and arrest.
