Abstract— A new approach to structural integrity assessment based on ductile fracture is explored in the present paper. A simplified, yet more convenient methodology than the conventional EPRI elastic-plastic fracture analysis is outlined which assesses the ductile fracture instability of structures by an intersection rather than a tangent construction. The J-equivalence principle of crack growth is employed for tearing instability determination of single edge cracked plates. An admissible stress curve method is established with a peak value indicating instability. This approach gives reasonable predictions concerning the burst pressure of pre-flawed pressure vessels. A theoretical J resistance curve, which is justified by experimental measurements for steels with relatively high yield strength, can be incorporated for a complete analytical characterization of the defect assessment procedure.
