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 thre

β¦ Synopsis
The propagation of damage fronts across pre-cracked components has been studied by use of continuum methods. It is shown that such an idealisation can be used to model the propagation of cracks when the behaviour is "creep ductile". In addition a technique for predicting the life of pre-cracked components emerges and it is shown to agree well with certain experimental data.

This investigation deals with the critical void growth in a BS4360 Grade 50D structural steel. The tests are carried out on four variations of the Charpy size specimens, namely a standard geometry; side grooved; fatigue cracked; side grooved and fatigue cracked. The geometry variations are intended
## Abatraet-Yokobori and colleagues have treated timedependent fracture, such as fatigue and creep fracture, as a stochastic process and a thermally activated process, extended the studies, and proposed the crack growth rate equations for fracture of various kinds. Among those for high temperature
