Luc Sibille proposed the following answer: Hello, I think question 2 can be seen as a real scientific question, in the sense that for a long time it has be assumed by many researchers that the softening after the peak was the consequence of the strain localization. That is why many phenomenological constitutive relations do not describe the softening after the peak. However, it seems that with DEM softening after the peak may be obtained without localization (for instance with a low number of discrete elements limiting the occurrence of strain localization). If the latter is true it would mean that softening could be seen as a constitutive response of a granular material. Nevertheless, I am sure there is a clear study around this question in the literature and probably it is still an open question... ?
