Application of statically indeterminate fracture mechanics, SIFM, to a circumferentially cracked cylinder problem Original Research Article

The method of statically indeterminate fracture mechanics called SIFM is an application of elastic–plastic fracture mechanics to statically indeterminate problems. Application of SIFM has been developed for axially cracked cylinder problems. Its application was modified to a circumferentially cracked cylinder. The component might be loaded by combined transient thermal and mechanical loading. This was applied to simulate pressurized thermal shock, PTS, experiment, NKS-3, carried out by MPA. The predicted result from SIFM shows good agreement with the NKS-3 experimental one.
