Rolling Contact Fatigue in Ansys Multiphysics

Hello all,

I want to simulate Rolling Contact Fatigue in Ansys Multiphysics. I am
not sure whether we can perform this task in Ansys Multiphysics. Can
anybody help me regarding this? Is that possible to get S-N Curve as
result? Please help me..

 If you want to make stress field of a rolling contact, the first step is to use ready closed form results. In fact, it is not obvious at all even with exact results, what you can apply to predict fatigue. See these papers

Hope this helps.

Mike gave you a good start point. If you are really looking at the analysis using ANSYS, these three papers might help. They include both S-N curve-based and fracture mechanics-based approaches. The focus is on the shattered rim failure (subsurface cracking) rather than surface cracking.

Hope it helps.


Thanks to both of you..I will get back when I need some more help! Thanks once again for valuable help..
