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

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.
