چکیده:

Constitutive plasticity models of granular soils which the effects of soil state has been taken into account in their formulation have shown very impressive capabilities in simulation of soil behavior over wide ranges of soil densities and overall stresses using only one set of material based model parameters. Herein, behavior of inclination angle of shear band using a state dependent plasticity model is studied. It is shown that typical simulations of behavior predicted by the model are in well agreement with the results of experimental studies of real soils.
