Diego Abarca posted a new comment: Thank you for your answer Jérôme, > I think it is the same in (granular) mechanics ! Indeed, from granular mechanics I know that for the shear phase of an undrained triaxial test there is a family of combinations of initial stress and void index where it would be expected that stresses drop. However, in laboratory tests with real soils under these conditions it would usually happen at larger vertical strains than the strain the model is experiencing when stresses drop to zero, the final stresses of the real soil would drop to small but nonzero values, and the effects of this drop would be smaller when starting from a lower void index. That was what I was expecting to happen when imposing an undrained condition by maintaining constant volume. I know this can be done in YADE as it has been used to simulate soil liquefaction [1], but there are many things I could be doing wrong as I don't know the specifics of how this was achieved. Thank you for your time Jérôme, I hope you have a nice day.
