Best creep model for ABS

[omoya]

Hi Experts,

I'm just starting to study how setup the material on ANSYS workbench to take into account the creep for PC+ABS material.

What it's the better model approach to consider?
I'm actually looking for prop. on material's Handbooks to capture points graphically on Strain-vs-time behaviour and then use a tabular fit model on ANSYS. Do you think that it's right?

Any recomendation?

Thanks in advance.
