Hello, Thanks a lot in advance for the kind and helpful reply. I am currently dealing with a ogden model, but I have 3 problems with it. I will show my code below after 2 questions. I do not know how to build up the fiber’s direction and the sheet’s direction in FEniCS. I used 2 Constant pairs bu…

Hi, Indeed computing an Ogden model is not straightforward due to the dependence on principal stretches. You can indeed compute them analytically in 2D but in 3D it is not possible. We recently developed an interface between FEniCS and the MFront constitutive behaviour code generator thourgh the M…

Hello bleyerj,

Yeah, I tried to compute ogden model directly. But it is very difficult indeed. Thank you so much for your resources and generous help!

Best,
Bill
