. In this work, we consider a mathematical model for granular medium. Here we
claim that reduced Cosserat continuum is a suitable model to describe granular materials.
Reduced Cosserat continuum is an elastic medium, where all translations and rotations are
independent. Moreover, a force stress tensor is asymmetric and a couple stress tensor is equal
to zero. In paper, we are aiming to establish a continuity conditions for nonlinear reduced
Keywords: granular materials; reduced Cosserat continuum; conditions on the surface of discontinuity.
