J-Integral Elastic Plastic Fracture Mechanics Evaluation of the Stability of Cracks in Nuclear Reactor Pressure Vessels

摘要

Contributions were made toward developing a new methodology to assess the stability of cracks in pressure vessels made from materials that exhibit a significant increase in toughness during the early increments of crack growth. It has a wide range of validity from linear elastic to fully plastic behavior. (ERA citation 05:032270)
