Abstract The strain energy partitioning(SEP)approach,namely,a modification ofstrain-range partitioning(SRP),has been developed to predict the creep fatiguecrack initiation life for GH33A Ni-base superalloy at 700℃ and 1Cr18Ni9Ti stain-less steel at 600℃.It shows that the life can be predicted by two variables:themaximum tensile stress and the partitioned inelastic strain-range,i.e.,the strain-range component in SRP is substituted by the strain energy component in SEP.The low-cycle fatigue data at elevated temperature for these two given alloys arecorrelated and predicted to within a factor of 2 using SEP,while some numeralsof data for GH33A beyond the factor of 2 using SRP.In addition,the predica-bility of SEP versus SRP has been evaluated by 8 other alloys of high-strengthand low-ductility.It would seem that SEP is an improvement over SRP.
