Plane strain elements work incorrectly in rolling process
Plane strain elements work incorrectly in rolling process
(OP)
When I use plane stress elements in simulation all works great. The picture below shows the results from my analysis with the use of that elements:

But when I change the type of elements to plane strain, the results are terrible. Look:

The only change I did is different element type. And results are completely confusing. Why the slab returns to its oryginal shape after it exits the roll gap?
Is it possible to fix it? I have to use plane strain elements.

Plane stress:
S11:
S22:
Strain intensity:
And plane strain:
S11:
S22:
S33:
Strain intensity:
How can I fix it?

But when I start the analysis, solver returns errors:
SOLIDSECTION REF. NODE 1204 INSTANCE Core material layer-1 IS NOT ACTIVE IN THIS MODEL
SOLIDSECTION REF. NODE 1204 INSTANCE Core material layer-2 IS NOT ACTIVE IN THIS MODEL
SOLIDSECTION REF. NODE 4805 INSTANCE Transition Layer-1 IS NOT ACTIVE IN THIS MODEL
SOLIDSECTION REF. NODE 4805 INSTANCE Transition Layer-2 IS NOT ACTIVE IN THIS MODEL
I have tried to define reference poins in the middle of the layers too, but errors did not disappeared.
What should I do?

I have never had to deal with input files, so I will stop now with this problem. First, I have to learn about working on input files.
So, thank you for your help corus. Maybe I will refresh this thread in the February.
