Numerical Simulation on Rolling Contact Fatigue with Dent at Rolling Surface

摘要

This work has investigated the effect of spherical dent on rolling contact fatigue (RCF). A 3-D finite element simulation model of bearing rolling contact incorporating critical plane approach has been developed to study the fatigue failure location. It was found that the fatigue failure locations were significantly influenced by the dent. The calculation results are in good agreement with the experimental results and comparable with the results from the published literatures in which 2-D models were generally used.
