Dear Moritz Jena,
No, unfortunately, plane stress versions of Hyperelastic laws has not been implemented yet. I would not be so difficult, but as to be made. If you need one in particular and have the expression, it is no so difficult to describe it with the weak form language.

The problem is three-dimensional, but can be reduced by plain stress approximation. (to reduce computing time). I want to define a nonlinear material with the brick gf_model_set(model M, 'add nonlinear elasticity brick', [...]) For this nonlinear command it is specified in the description, that in 2D always plain strain is used. So my question is: Is there a way to define a nonlinear material with the plain stress approximation? Or is it planned to install such an option in a future release? I hope you can help me with my problem. Best regards, Moritz Jena
