Hello,
I am working on a wear simulation of tillage tools. I need a particle bed for the process simulation. The particle bed is supported at the bottom by a geometry element. At the sides, however, periodic boundaries are used for support.
Now to my actual problem:
The geometry element at the bottom should not actually participate in the wear process, as it only serves to hold the particles in position above it.
Initially, I only defined interactions between the particles and the tool material (wear constants, hardness, ...).
Accordingly, no interaction parameters were set for the base plate material.
Nevertheless, the geometry of the base plate wears very heavily (or even disappears completely in some cases) from the first contact with particles. Even if I define interaction parameters for the base plate or change the mesh fineness, this can only help to a limited extent.
In comparison, the Archard Wear model works correctly.
Is the problem with the Oka Wear model known or is there a solution?
I have attached an adapted simulation file which shows the problem.
Best regards
HE
