The aim of this study is to provide a solution for the plastic limit pressure and stress intensity factor of the elbows containing a part-through axial semi-elliptical crack by considering various crack sizes. The supporting system and loading conditions of the pipeline are described. The critical part of the observed pipeline was isolated for anal...

... comparison shows that trends in both sets of results are consistent (Table 2). As the crack depth or geometry changes, both the FEA results for the elbow and the analytical solutions for the straight pipe exhibit similar trends in pressure reduction. ...Context 2

... FEA approach effectively captures the mechanical behavior under similar loading conditions. The results presented in Table 2 are used to plot the variation in stress intensity factor and plastic limit pressure against crack length and pipe thickness ratio (a/t), with respect to the crack dimension ratio (c/a). These plots are illustrated in Figures 7 and 8. ...
