FE Results: Conductor The results obtained from the numerical analyses with the initial crack length equal to 3.92 mm (maximum crack depth) and the stress range of 80 MPa are shown in Fig. 8 and Fig.9. Figure 8 : Comparison between FE and analytical SIFs for initial crack length 3.92 mm (K IC = 7115 MPa  mm). Figure 9 : Comparison between analytical and FE residual life estimation for initial crack length 3.92 mm.
