摘要

The small-scale steady-state (S4) test, evaluating rapid crack propagation (RCP) performance, is now an international standard for the specification of polyethylene fuel-gas distribution pipe. There is an emerging consensus, amongst users andmaterial developers, that RCP must be guarded against and that the S4 test is useful for doing so. Argument continues, however, about the S4 critical pressure requirement, P{sub}cS4 which should be specified to qualify pipe for a given operating pressure. Due to the complexity of the phenomenon, the use of numerical simulation is inevitable. The numerical model has to account for the dynamic deformation and fracture of the structure, the gas dynamics of the pressurising medium and their interaction.
