Steady-state algorithm in Ansys
Posted in the ANSYS Forum

Could someone help me with the following subject?
I'd to calculate the residual stress and strain fields during a repeated rolling contact of a body over a flat surface using an elastoplastic model.
The way I know to solve this is simulating many passes (translates the loads). This kind of approach is time-consuming and cumbersome! If you are working with 3D models (my case) the problem becomes very difficult.
A researcher called Dang Van proposed a method based on steady-state algorithm, where you can find the complete stresses and strain fields for one load pass without moving the loads incrementaly (something like the reference frame moves with the loads). To obtain the complete stress field for one pass (1 cycle) in the entirety model , you have to apply the loads just once.
So, I think Ansys can't do this kind of analysis. But I have the
algorithm and, if it's possible, I can implement it in Ansys code.
Do somebody knows something about this and could help me?
My best regards,
