Abstract
Heterogeneity of granular materials triggers shear zone formation. In the paper, the FE-analysis of the effect of heterogeneity on the formation of a spontaneous shear zone inside of granular material during a plane strain compression test is presented. The numerical calculations are performed with a finite element method on the basis of a hypoplastic constitutive law extended by polar quantities: rotations, curvatures, couple stresses and a mean grain diameter used as a characteristic length. The heterogeneity in the granular body is assumed in the form of spots with a different initial void ratio. The spots are single and distributed randomly or stochastically.
