See I did two identical tests.
In one, a SPH die of aluminum is drilled, in the second of concrete and sandstone.
Aluminum cuts well, but it does not cut concrete and sandstone.
Aluminum uses Johnson-Cook + EOS material.
Mohr-Coulomb sandstone and Drucker-Prager concrete.
Why are sandstone and concrete not drilled?
I also wanted to add a map snippet with other stuff that takes EOS into account:
But the LS-Dyna ACT workbench gives an error:
LS-Dyna prepost on such material gives an error:

you can insert the material snippets as commands to specific to the part. Parts are serilised in the WB
you need an damage accounting to the Mohr-coulomb as the material model is updated recently,

I used the sandstone material from the WB base with More-Columbus. But it also doesn't wobble.
I found my mistake: the snippet-material needs to be inserted into the geometry part.
But why doesn't the stuff work in LS-Dyna prepost (not WB)?
And in the Workbench, an error will appear on "_TITLE" in the title of the material.
After failing the sandstone and concrete materials from the WB base with More-Columbus, I decided to try the Johnson-Holmquist material.

Fine. it all worked. it was necessary to insert the LS-Dine snippet CONTROL_CONTACT.💯
But Johnson-Holmquist material does not work in LS Prepost.
