【 摘 要 】

Fracture mechanics methodologies for flaw stability analysis for Type I and II waste tanks were compared in terms of the maximum stable through-wall flaw sizes or instability lengths. The comparison was made at a full range of remote stress loading states at a specific set of mechanical properties of A285 steel and with the Type I and II tank configurations. The two general methodologies, the J-integral-tearing modulus (J-T) and the failure assessment diagram (FAD), and their specific estimation schemes were evaluated.
