Viscoelastic material model
Viscoelastic material model
(OP)
Hi Everyone,
Does anyone know of any ANSYS material model files for nonlinear materials such as polymers. I am trying to model the deformation characteristics of an epoxy pressed up against a rigid body. The nonlinear capabilities in ANSYS require input of data for curve-fitting - I don't have such data. I need a generic material model specifically for viscoelastic materials.
Can anyone help?
Thanks,
icefea

Thank you for your reply. You are right, there is no such thing as a generic material model for viscoelastic materials. I perhaps should have phrased this differently. What I am in fact looking for is a library of material models for viscoelastic/viscoplastic materials. If I find a model for a polymer similar to the one I am trying to model, I will use this as a template and modify/agument as necessary. Do ANSYS have such a library of material models?
