By making use of plastically adjusted linear elastic fracture mechanics analysis and plastic limit load solutions, a method is developed for reasonable approximation of Rice's path independent J integral which is applicable for test specimens or othe

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 fied. This together with the fact that J can be evaluated experimentally, makes a critical J value an at

A blunt-notch fracture criterion is proposed. The criterion is shown to be applicable for the initiation of ductile tearing in the plane-strain regime. Elastic to fully plastic behavior can be treated. Experiments have shown ductile crack initiation

This report presents a detailed evaluation of the rising load, accelerated K I s c c testing procedure proposed by McIntyre and Priest. Conventional long hold-time "bolt loaded" K I s c c tests were conducted with 160 and180-ksi yield-strength Type 4

A fracture mechanics approach was used to study high-temperature creep crack propagation. Crack growth rates were correlated with the C*-parameter which is an energy rate line integral. For materials conforming to a nonlinear stress and strain rate r
