I'm using a Workbench Ls-dyna (student account).

I want to set a material on each plane.

But there is no few material model, equation in the engineering data.

I want to add the material below

Copper

-       Steinberg material model

-       Gruneisen equation

Steel

-       John-Cook model

Shaped-charge Explosive

-       Mat_High_Explosive_Burn material

-       JWL equation

ERA Explosive

-       Ignition-and-growh-of-reaction-in-HE equation

But i couldn't find a Steinberg, Mat_High_Explosive_Burn, Ignition-and-growh-of-reaction-in-HE

How can i add it?

(I'm a beginner)

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, Ram
