โœฆ Synopsis

Numerical results of the J-integral are obtained by elastic-plastic finite element analysis for an external, axial crack in an internally pressurized cylinder whose material exhibits a large yield plateau in the true stress-strain curve. Comparisons are made with the EPRI J-estimation values by three different Ran&erg-Osgood approximations. The yielding and hardening behaviours in the vicinity of the crack tip under internal pressure are analysed by means of finite element results. Finally, the applicability of the EPRI procedure for the material is discussed.

In the transition regime plain strain crack propagation in ferritic steels proceeds by a combination of cleavage and ductile rupture processes, the latter being confined to ligaments that are parallel to the direction of macroscopic crack propagation. These ligaments rupture as the crack propagates,
