For open-end cylinders with hoop cracks, as well as for both open-end and closed-end cylinders with axial cracks, no analytical solutions have been proposed yet. The results of the FE analysis for these cases are presented in figures 6 and 7 respectively:

Finally, the influence of residual stresses on the limit curves for open-end and closed-end cylinders with external circumferential (hoop) cracks can be seen in figure 8:
