A simplified method for creep-fatigue life prediction for structures subjected to thermal loadings Original Research Article

A simplified creep-fatigue failure prevention-life prediction method (TTSDS) for pressure vessels and pipings subjected to thermal expansion-thermal transient loadings is presented. The method was constructed based on numerous SUS304 material-structure test data, and incorporates a linear cumulative damage rule with an instrinsic life reduction factor. When the TTSDS method was applied using no safety factors, good life predictions for piping elements-components subjected to cyclic thermal transient loads were achieved.
