Hi Thomas The tut is fully non-linear incompressible elasticity (geometrical and material nonlinearities). It can also be used for compressible hyperelastic material models. Satisfying the incompressibility constraint is the main challenge: we use a three-field formulation.
Luca had contributed a un or partially documented tut on geometrically linear (if I recall) elastoplasticity. As I said, I hope to be able to make some progress on this early next year.
