Hello folks,

I have a quasi-static compression curve for a material and would like to use the Ogden Foam 3rd Order hyperelastic model implemented in Ansys. Does anyone know how to curve fit it? This model has 9 params and I don't know how to find them.

If I were to use the Ogden 3rd Order (not the foam one) it would be ok, since it’s just a matter of creating a new material in the Engineering Data toolbox (workbench), use the Uniaxial Compression Test Data as a new material property, then drag the Ogden 3rd Order and realise over this new property. At this point a “Curve fitting” option appears. The same option does not appear for Ogden Foam 3rd Order model. Did somebody use this material before?

Ps.: Using Ansys 17.1
