Dear all,
The structure I would like to model is made of PMMA: E = 3.2 GPa, nu = 0.4. More parameters are in the uploaded image:


When modelled as linear elastic, the obtained results are different from the experimental ones.
At this stage of our project, I would like to consider a (linear or nonlinear) viscoelastic model.
Here, I want to know what parameters to enter to abaqus to be close to a very common PMMA material ?

Regards,
 
The choice of material model depends also on the type and rate of loading. In some cases a hyperelastic model can be sufficient for such materials. If you want to account for viscous effects as well, you will need proper test data for viscoelastic model.
