CONTAINED IN VOL: 03.01 2000Determines fracture toughness as characterized by the J-integral. Three toughness properties are identified which vary with the amount of crack extension present at test termination: (a) instability without significant prior crack extension (J); (b) on set of stable crack extension: (J); (c) stable crack growth resistance curve (J-R). A fourth quantity not currently interpretable as a toughness property may be measured at fracture instability following stable crack extension. Applies specifically to geometries containing notches and flaws sharpened with fatigue cracks. Loading rate is slow and environmentally assisted cracking is assumed to be negligible.
Supersedes ASTM E 813 and ASTM E 1152
