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.

Jorgen,
thanks for your reply.
I do not regretfully have nay experience in user defined materials. Might be a good occasion to start thinking about it and take my Fortran out of the lost things room.
Have anice Sunday

Hi,
anisotropic hyperelasticity AND viscoelasticity is not yet supported, only the isotropic case. This will be the case in v12 of ANSYS
