transverse isotropic and viscoelastic

[qiangbo]

Hi,

After reading abaqus manual, it seems that the time constants are the same for both directions of transverse isotropic materials. Is it true? Is there a way to make time constants independent for the two orthogonal directions? Thanks!

Why don't you embed elements? That way you can have different time constants for each embedded layer and not have to worry about writing subroutines.

Thanks!

It seems like an very interesting option. Are there examples about how to use embedded elements to model anisotropy + viscoelasticity?

Thanks

Just anisotropy.
