Figure 8. Diagram force-CMOD for specimen 500-51

Figure 9. J -integral resistance curve for specimen 500-51 The procedure for determining the CTOD-R curve is similar to the previous procedure, and parallels are drawn on the diagram at = 0.15 mm, 0.2 mm, and 1.5 mm. The results are given in Figure 10. Table 7. shows the main results of the fracture mechanics test: J IC ,  IC and K JIC . Table 7. Main results of the fracture mechanics test
