Orientation tensors taken into account?

Hi, does this software take orientation tensors into account?

Say I want to calibrate a material model for a fiber filled engineering polymer and use in Abaqus where the experimental data has been measured on molded plates. I can figure out, or at least estimate, the orientation tensors through a Moldflow evaluation. Alternatively I can measure the real fiber orientations using CT Scan data. The experimental response in the different angles will not be with a 100% alignment in that direction.

Is there any way I could use the PolyUMod software to calibrate an an-isotropic (or orthotropic) material model using this data. Are any of the available material models suitable for use with fiber reinforced engineering thermoplastics, I saw in the support section that a lot of material models are available, but most of them seemed to have been developed for isotropic material types.

Thanks

Best regards

Hello,

The PolyUMod library has multiple material models that can model anisotropic materials.  I would recommend looking at the Flow Evolution Network (FEN), the Three Network Viscoplastic (TNV) model.  The Parallel Network model can also support anisotropic materials.
