“…Once such functions are found, see for instance Rahman et al (5) , the proposed Ramberg-Osgood fitting procedure would provide accurate J estimates. For the reference stress approach, on the other hand, the effect of internal pressure on elastic-plastic J estimates has been discussed elsewhere (10) , and detailed information can be obtained therein.…”

“…Reliable estimates of the elastic-plastic J-integral and crack opening displacement (COD) for circumferential through-wall cracked pipes are essential to the LeakBefore-Break (LBB) analysis (1) - (10) of nuclear piping. In Part I (11) , the authors have proposed methods to estimate elastic-plastic COD for circumferential through-wall cracked pipes.…”

The present work presents a method to estimate elastic-plastic J for circumferential through-wall cracked pipes for the Leak-Before-Break (LBB) analysis of pressurized piping. The proposed method is based on the GE/EPRI approach and the key issue is to propose a robust Ramberg-Osgood fitting procedure. Two different estimation schemes are given, one for the case when full stress-strain data are available, and the other for the case when only yield and ultimate tensile strengths are available. The proposed J estimates are compared with those from extensive elastic-plastic finite element (FE) analyses. Experimental validation is also performed by comparing maximum moments predicted by fracture mechanics analysis using the proposed J estimates with those from full-scale pipe test. Both results show sufficient confidence in the accuracy of the proposed J estimates.

“…On the other hand, available solutions (6) - (8) are still limited to certain pipe/defect geometries and in particular to the loading mode. For instance, those functions for combined tension and bending or for combined pressure and bending are yet limited for practical application, see for instance, Rahman et al (8) On the other hand, the reference stress approach can be easily extended to more complex situations, for instance, for combined tension and bending (23) and for combined internal pressure and bending (24) . Moreover, the COD estimation equations based on the reference stress approach are simple to use, which is also useful in practical applications.…”

The present work presents methods to estimate elastic-plastic COD for circumferential through-wall cracked pipes for the Leak-Before-Break analysis of pressurized piping. Proposed methods are based not only on the GE/EPRI approach but also on the reference stress approach. For each approach, two different estimation schemes are given, one for the case when full stress-strain data are available, and the other for the case when only yield and ultimate tensile strengths are available. For the GE/EPRI approach, a robust way of determining the R-O parameters is proposed, not only for the case when detailed information on full stress-strain data are available but also for the case when only yield and ultimate tensile strengths are available. The COD estimates according to the GE/EPRI approach, using the R-O parameters determined from the proposed R-O fitting procedures, overall compare well with the published pipe test data. For the reference stress approach, the COD estimates according to the method based both on full stress-strain data and on limited tensile properties are in good agreement with pipe test data. In conclusion, experimental validation given in the present work provides sufficient confidence in the use of the proposed method to practical LBB analyses, even when information on material's tensile properties is limited.
