I'm new in ANSYS simulations so maybe my problem is really trivial. 3
I have to simulate impact test of foam specimens in ANSYS Structural using Ogden material model(have to use Ogden model). I know that I need all coefficients to use (TB,HYPER,,,FOAM) function. I was trying curve fitting tools in different programs(also SolidWorks and Autodesk Algor Simulation) but couldn't obtain good approximation. I have uniaxial tension and compression stress-strain data but as I know model fitting for compression should be enough.
Is there any other way to obtain material model coefficients than tools I've been using? Maybe ANSYS also can help me if I have experimental data only or maybe I should find other program?
I would be really grateful if anyone have idea what I should do know. I can't start simulations without reliable material model.
Thanks in advance,
