General Creep-Fatigue Life Prediction Models, J. Toland, Tarun Goswami

Biomedical, Industrial & Human Factors Engineering Faculty Publications

This paper presents a data bank that was compiled from published and unpublished sources. Using these data, low cycle fatigue curves were generated under a range of test conditions showing the effect of test parameters on the Coffin-Manson behavior of steel alloys. Generic equations have been developed in this paper to predict the creep-fatigue life of high temperature materials. Several new multivariate equations were developed to predict the creep-fatigue life of following alloy groups; I) Cr-Mo steels, 2) stainless steels and 3) generic materials involving the materials from the following alloy groups, solder, copper, steels, titanium, tantalum, and nickel based …
