Non-associated Cosserat plasticity
Frictional plasticity models with a non-associated flow rule, ubiquitous for describing failure in geomaterials, can lead to a local loss of ellipticity for low hardening rates, i.e. before entering a strain-softening regime. This leads to an excessive dependence on the spatial discretisation and to...
