In the previous 2nd and 3rd Reports, the method proposed in the 1st Report to evaluate the Fracture resistance of a stable growing crack by crack energy density was applied to the stable crack growth problems of thin plates, and its applicability was confirmed. In this report, the fracture resistances based on the J-integral are evaluated using the experimental data obtained in the 2nd and 3rd reports. They are compared with the fracture resistances evaluated before by crack energy density and the superiority of the proposed method is shown through the comparison. The results are as follows: (1) The fracture resistances by the J-integral at the initiation of crack growth almost accord with those by crack energy density, as was predicted before. (2) The change of the fracture resistance of a growing crack evaluated by the J-integral does not correspond to the change of the fracture mode, although the fracture resistance by crack energy density varies corresponding to the change of the fracture mode.
