Abstract
In most instances, dynamic fracture mechanics analysis of structural components can safely assume that external loads are independent of the crack propagation and arrest event. However, for pressure vessels and pipelines this will not usually be the case. Here the flow of the contained medium through the crack opening will play a large role in dictating the crack driving forces. Typical of this important class of problems is rapid axial crack propagation along the length of a gas transmission pipeline. A computational model has recently been developed for the accurate analysis of this problem. This model accounts for the high degree of coupling between escaping gas and the pipe walls during the propagation event.
