Quantification Of Three-Dimensional Elastic-Plastic Crack-Tip Stress Fields

Conventional structural integrity assessments are formulated based on plane strain fracture toughness to provide a conservative estimate of failure. However, such approach often leads to unnecessary repair and shutdown of structures. This conservatism has been minimized by the two-parameter fracture...
