Can Higher Strain Rates Be Modeled from Existing Stress/Strain Curves?

[fsh1962]

I want to create stress/strain curves for Higher Strain Rates from an available stress/strain curve?
I am interested on the mathematical formulation aspect to generate a Dyna Material card.

You are not talking about the intrinsic stress/strain behavior of the material, correct? You are talking about applying a nominal high strain rate to a bar and trying to determine the nominal stress/strain response, correct?
