A procedure for application of finite element analyses (FEAs) for the limit load assessment was investigated for the fitness-for-service code for nuclear facility by the Japan Society of Mechanical Engineers. The current code prescribes the equations

The current JSME rules on Fitness-for-Service only applies the Elastic Plastic Fracture Mechanics (EPFM) method, including the two-parameters method for flaw evaluation of cast stainless steel (CASS) pipes, while plastic collapse is expected to occur

Fracture strength of cracked pipes made of moderate toughness materials is derived using J-integral value, which represents the driving force for fracture, and J-R curve, which corresponds to the material strength. However, in practical applications,

Performance demonstration certification of non-destructive inspection for cast stainless steel (CASS) has been planned but the target flaw depth to be detected has not been determined yet in Japan. The target flaw size is closely connected to the all

Thermal fatigue may occur in a pipe with high temperature stratified flow. To avoid the fatigue damage by the stratified flow, it is important to know a history of temperature and thermal stress distribution in the pipe. This paper describes a heat c

In order to predict fracture behavior of a structure with low constraint, tensile fracture tests using flat plate specimens with a surface flaw were performed at −80°C and −120°C in the ductile-brittle transition temperature (DBTT) region. The
