Validity of J-R resistance curve in the case of ductile crack growth
The validity of J-R resistance curve by CCT fracture toughness specimen with significant ductile crack growth has been evaluated. It was found that far-field J-integral loses its ability to unambiguously correlate crack growth after crack initiation. Therefore, J-integral values should be taken very careful after crack initiation. However, if the crack growth is mainly J-controlled, the J-R curve may be considered as valid and as material property.
