Abaqus wear subroutine

Abaqus wear subroutine

Abaqus wear subroutine

(OP)
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

RE: Abaqus wear subroutine

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.love

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