The JSME Committee on Power Generation Facility Codes is developing a fatigue evaluation method by flaw tolerance. The ASME B& PV Code Section XI has Non-mandatory Appendix L, which provides a flaw tolerance method for fatigue evaluation when a cumulati ve usage factor (CUF) of a component is greater than 1.0. In order to develop a flaw tolerance method for the JSME Codes, post ulated initial flaws, capability of nondestructive examination, compatibility to rules and flaw tolerance codes are discussed....

Development of Fatigue Evaluation Using Flaw Tolerance Method

In order to develop and propose new design fatigue curves for austenitic stainless steels, carbon steels and low alloy steels that are rational and ha ve clear design basis, Design Fatigue Curve (DFC) subcommittee was established in the Atomic Energy Research Committee in the Japan Welding Engineerin g Society and the study on design fatigue curves are going on. The fatigue curves are proposed as a function of their tensile strength based on large number of fatigue data tested in air from room temperature...
