*1. _()(1)Assumption in the developed model _ ()The overall deformation originates from the deformation of the layers (microplanes) among sand particles.
The strains on any micoplane are the resolved components of the macroscopic strain tensor, which represents a kinematic constraint.
The deviatoric and shear responses are mutually independent.
