Abstract: The evaluation of J-integral from experimental data requires the ηpl and γ functions. However, these functions are available for limited geometry in the literature. In this paper, limit-load-based ...

Abstract: Elastic-plastic finite element analysis has been carried out to evaluate collapse moments of six elbows with elbow factors varying from 0.24 to 0.6. The loading conditions of combined in-plane ...

Abstract: A large throughwall circumferential crack in an elbow subjected to in-plane bending moment can significantly reduce its collapse load. Therefore, it is very important to know the collapse moment ...
