How to get Holzapfel-Gasser-Ogden (HGO) Model?

Peter Andreas Timotius_20357

Hello, 

I am dealing with finite element simulation of ligaments. I expect to perform a simulation with Holzapfel-Gasser-Ogden model, as it is commonly utilized for biomechanical models. However, what I've learned now is that Hyperworks only provides Ogden model (under MATHE --> OGDEN), which I think it doesn't resemble HGO model (HGO model is a modification of Ogden model).

Thus I would like to ask, how can I prepare my material with HGO model and its coefficients? Thank you for your kind concern.

Hi Peter,

Below are the material model list Optistruct supports under MATHE. I did not find HGO model, so this is not yet supported in Optistruct.

Thanks
