Abaqus wear subroutine 2

[matmeanla]

Dear experts;
I want to do a wear simulation incorporating the UMESHMOTION subroutine.
I have tried the simple model to model the wear in Abaqus, but I still stuck to produce wear and get the wear volume. I want to try the simple geometry.
The idea is , a rotating cylinder is loaded onto a flat surface so that this will give the contact between two body.
Then will generate wear on the surface. Maybe from your experience you can help me. Here I attached the the file related​

the subroutine

I really hope the experts here can solve my problem. Thank you

What is the wear law you are modeling? If you can exploit symmetry, then you must take the route that is discussed in the documentation; it is an example on tire wear.

I model wear once. I could reproduce the simple model of the next thesis:

Here there is a code for the subroutine. Everything is carefully descripted. It is a great work.

If you are starting to use UMESHMOTION, I advice to you to start with a plane strain/stress model wich is more efficient.
Higlights for wear that I remember:
- The mesh should be very refined to reproduce correctly the hight concetrated gradient of stresses. You can check the mesh convergence with the Hertz contact formulas.
- You can only access to the slave node data using the subroutine.

IceBreakerSours (Bioengineer). Thank you for the replied. I use Archard Law for the wear and Hertzian contact .
Yes, this is my first post and my first time joining the forum.

Thank you for the information. I ll try it now.
