Abstract : The J-integral, which has been heralded by many as a stable crack growth and ductile fracture criteria and which in its linearly elastic limit becomes the strain energy release rate, derives its popularity in being a path-independent integral. The purpose of this paper is to review an experimental procedure, which was developed by the authors, using more interferometry, for estimating the J-integral values along contours inside fracture specimens and to present some resistance curves, R-curves, of aluminum single edge notched (SEN) specimens.
