Book excerpt: The path independent J integral, as formulated by Rice, can be viewed as a parameter which is an average measure of the crack tip elastic-plastic field. This together with the fact that J can be evaluated experimentally, makes a critical J value an attractive elastic-plastic fracture criterion. The JIc fracture criterion refers to crack initiation under plane strain conditions from essentially elastic to fully plastic behavior.
