Elastoplastic realization question

[RokyC]

Hello, I'm very excited that libraries like dolfiny make it easier to implement universal material constitutive under fenicsx. I was wondering if you could share a tutorial on viscoplastic constitutive variational theory? Because while I learned in the demo program, the dλ = ufl.max_value(f, 0) and the reinforcement criteria represented by bh, qh, bb and qb on solid_plasticity_monolithic.py are somewhat unclear.Thanks very much!

It would be good just to add any reference book or paper.

Thanks for your feedback. I have added some references and further comments directly in the demo code, that could be helpful.
