[Turning linear deformation into large deformation using Mooney-Rivlin equation]

[ygke...@gmail.com]

Hello,

I am currently trying to adapt the script linear_elastic.py to use it with large deformation, involving Mooney-Rivlin equations. I tried to get some inspiration from the balloon.py and hyperelastic.py scripts, but though I modified the sections : equations, solvers, parameters to try to fit Mooney-Rivling equations' recquirements, it does not work.

My question is therefore : Has anybody an idea to turn properly the script linear_elasticity.py into a model using large deformation ?  Thank you for your help.

The hyperelastic.py is already an example with the Mooney-Rivlin material
model. Why don't you start from that?

Can you specify what "does not work" means? An example script would be handy.
