A classical analysis of Irwin and Corten relates the minimum pressure to sustain crack propagation along a pipeline to the dimensions, elastic modulus and fracture resistance of the pipe wall. Although the model is inapplicable to gas pressurisation, it is here modified to become sufficiently accura
## A new small-scale test method has been developed for generating steady-state rapid crack propagation in plastic pipe. Using this method, a series of exploratory tests are used to investigate the variation in critical pressure (i.e. the threshold of crack self-arrest) with parameters which are s
Experimental pressure histories, axial and circumferential strains, and crack-opening shapes were compared with the predictions of a simplified model of a fracturing pipe. This model, based upon previous analytical and numerical studies. assumed that the axial strains were negligible. The comparison
