Notes:
The present work proposes a method for elastic-plastic fracture mechanics analysis of thecircumferential through-wall crack in between elbows and attached straight pipes, subject to in-planebending. Based on small strain finite element limit analyses, closed-form limit load solutions aregiven first. Then applicability of the reference stress based method to approximately estimate J isproposed. One interesting finding is that a popular approach to assume that the crack locates in thestraight pipe could lead to significantly different assessment results
