Orthotropic viscoelasticity?

Hi All,

I routinely model a composite material smootheing it using classic mixture rules, hence defining a homogeneous orthotropic material.

Is there a way to introduce rate dependency into this approach in ANSYS?

I went thorugh the documentaion with poor results.

Thank you

I think the latest version of Abaqus supports that through anisotropic hyperelasticity + linear viscoelasticity. I am not sure if Ansys supports anisotropic viscoelastic materials yet. Anyone who knows more?

An option, as always, is to use an anisotropic viscoelastic user-material. I frequently do this with Abaqus, but it should work fine with Ansys as well.
