Rolling contact fatigue in refurbished case carburized bearings

This paper presents a continuum damage mechanics-based elastic-plastic FE model developed to quantify the rolling contact fatigue (RCF) life of refurbished bearings made from case carburized steel. Using the model developed for this investigation, case carburized steel fatigue performance was compar...
