The constitutive equations of a two-dimensional flow theory of plasticity for granular materials with Cosserat structure are outlined. The post-failure behavior is modeled by means of softening rule that is based on a two fractions mixtures theory for sand. The paper is focusing on the two major bifurcation phenomena observed in element tests, i.e. shear-banding and liquefaction.
