Slave deformable surface penetrating Master rigid surface

Slave deformable surface penetrating Master rigid surface

Slave deformable surface penetrating Master rigid surface

(OP)
Hello,

I am modelling a rolling simulation. The roller is an analytic rigid body and the workpiece is deformable with C3D8R elements.

The contact is Surface-to-Surface contact (Explicit). I cannot figure out how to prevent the workpiece from penetrating the analytic rigid.


I was hoping someone could explain why this is occurring. I am looking into mesh refinement and modelling roller as discrete rigid as possible solutions.

Thanks

RE: Slave deformable surface penetrating Master rigid surface

Perhaps you've not defined the surfaces correctly. Plot CPRESS or COPEN to see where contact is being made.
