Hey everyone,  
There is a great implementation of nonlinear Timoshenko beams in FEniCS [Nonlinear beam model in finite rotations](https://comet-fenics.readthedocs.io/en/latest/demo/finite_rotation_beam/finite_rotation_nonlinear_beam.html), however, this only accounts for large rotations.  
I was wondering if some of you have looked at an implementation of plastic beam elements through a hinge approach, like here in OpenSees [OpenSees: Beam With Hinges Element](https://openseespydoc.readthedocs.io/en/stable/src/beamWithHinges.html) or here a paper on that [Plastic Hinge Integration Methods for Force-Based Beam–Column Elements](https://doi.org/10.1061/(ASCE)0733-9445(2006)132:2(244)).

If you can give me a hint, whether this type of implementation would be possible in FEniCS, that would be great.

Thanks!
