Hi, 

I am not sure what version of ANSYS you are using here, but Johnson cook is supported natively and in the newer version, EOS JWL, GRUNEISEN are supported.

However, for the combination of material model and unsupported EOS, you need to use the command snippets specific to the plates , check the link /forum/forums/topic/ansys-workbench-ls-dyna-material-command-snippet-causing-error/ on procedure 

For  Steinberg material model, see material model 011.

Cheers, RamÂ
