UHYPER for Multiple Materials

[jdmay]

I am modeling the layers of an artery (intima, media, adventitia). Each layer is a third order Mooney-Rivlin hyperelastic material model. The materials vary by the coefficients for the Mooney-Rivlin model. How can I write the UHYPER subroutine so that the correct coefficients are applied to the correct layer?

Create a different material definition for each layer. Pass the constants in for each through the 'props' array.

That is what I had in mind. I just wasn't sure about it. Should I replace CNAME with the material name that I am using in Abaqus?
