I'm having difficulty finding material definitions fitting a viscoelastic foam within ansys or within the many online resources.
Using Prony seems an absolute must, however I do not have data to input in order to model viscoelasticity. Ideally, modifying structural steel NL would serve as a great start.

It looks like question on ANSYS. Should I move this to Structural Mechanics so that you would get better reply.

Great suggestion! If you think it will help, I would appreciate it.

Ok. Then I am moving this to Structural Mechanics category.

I would recommend you to axelproducts or datapointlabs for material data.
Yes, you would need to fit the data using prony-series parameters.
You might want to fit your data to a hyper-elastic material model such as Ogden 3rd or 4th order first? Structural Steel behavior is no way close to how a foam material would behave. One of the biggest challenges in capturing Foam materials is to account for the incompressibility.
For just hyper-elastic data we have a group of materials you can start with in Engineering Data Sources itself.
