34 ramberg osgood plasticity #45

Open pdiercks opened 8 months ago

pdiercks commented 8 months ago

Hi @srosenbu ,

this is a draft for the ramberg osgood example. It's now working with dolfinx version 0.6.0, but the formulation is not incremental and the compilation of the forms has to be explicitly called by the user at the moment. Also, I would like to reduce the complexity and remove certain parts of the code that are not necessary here.

We could also have a talk in the next days and add a general fenics_constitutive.interfaces.IncrSmallStrainProblem, such that the class is simply imported here (and potentially in the other examples).

Also, I did not generate the documentation yet.
