Figure 5. Severity evolution versus crack depth for the closed crack scenario. Figure 5. Severity evolution versus crack depth for the closed crack scenario. Furthermore, we determine the severity values for open cracks, considering the results presented in Tables 3–5. The severities calculated accordingly are depicted in Figure 6, along with the severities for the closed cracks for comparison. One can observe that an increase in the damage width has as a result an increase in the severity. However, the curves have the same
