Abstract

Finite element analyses were conducted to evaluate stress corrosion cracking (SCC) growth behavior based on J integral. The simplified method to calculate the J integral for four-point bending test was proposed. The J integral was calculated based on load-displacement curve and strain at the surface of tensile side in the proposed simplified method. The stress distribution ahead of crack tip was normalized by the J integral irrespective of loading condition and crack length. Thus, the J integral was effective for evaluation of SCC growth behavior.
