I don't know if this is the correct place to discuss this but many applications could use quadrature rules using vertices as quadrature points e.g. the already implemented `"vertex"` scheme...

Hi @tamaradanceva , If I am not mistaken Cosserat models (elastoplasticity in particular) should be straightforward to implement using `TFEL/MFront` and the `mgis.fenics` module since generalized stresses are just a...

Hi @RaffaRus, I think that this could be feasible right now. Could you share with us your best attempt and we can have a look and get back to you....

Indeed, there seems to be only partial support of Tensor/Tensor tangent blocks in MFront which makes straightforward implementation of Cosserat EP behaviour not possible right now. This should be fixed...

hi, here is a first proposal which compiles with the current master. I didn't check it yet though [CosseratIsotropicLinearHardeningPlasticity.mfront.txt](https://github.com/thelfer/MFrontGenericInterfaceSupport/files/5469284/CosseratIsotropicLinearHardeningPlasticity.mfront.txt)

yes, I was just sending this quickly, I had my kids around... I'll get back to it this week

OK, let me know if you need some help on the FEniCS side, in particular it may be possible that the Cosserat model needs some reduced integration strategy to prevent...

> @bleyerj, come mine too. Also, was not sure if the proposed algorithm is fully implicit or fully explicit... That's why I proposed to start write a small paper to...

dear @tamaradanceva and @RaffaRus , as discussed today with @thelfer, it seems that : * you did not consider coupling tangent terms dsig/dkappa and dmu/deps which should be considered for...

@tamaradanceva @RaffaRus Thanks to @thelfer explicit implementation, I have now a working example using `mgis.fenics` with the SNES solver using Newton method (with the elastic operator) and a line search...
