I don't think multilinear isotropic hardening and Hill yield combined with orthotropic elasticity is supported in Explicit Dynamics and LS-DYNA. In LS-DYNA, you can open the input.k file in a text editor to check what material model that is used.
At Ansys 2023R2, there is a new orthotropic strength material model for Explicit Dynamics:
You can define orthotropic strength coefficients (A11 - A66) along with a master Stress-Plastic strain curve. See image above.
You will find more information here:
There is information on how to obtain and calculate the coefficients here:
This information is in the Composite modelling guide for Autodyn:
This model can be combined with orthotropic elasticity.
In LS-DYNA, *MAT_PAPER (*MAT_274) could be used. Here is an excerpt from the LS-DYNA User Manual Vol II:
You can download the LS-DYNA manuals here:
Note that *MAT_PAPER is not available in Ansys WB yet, but you can include it in your model using a command snippet or using the Keyword Manager. You can use *PART_COMPOSITE to build the composite layup with *MAT_PAPER using a command snippet as well.
Let me know how it goes.
