| Popis: | The authors study numerically a problem on vortex flows in bounded domain in granular material using discrete element method. The granular material is composed of spherical particles with the assigned distribution of radii. Dry friction and rolling resistance at particle interfaces are taken into account. The kinematic patterns of granular material specimen deformation are described, and the trajectories of some particles are shown. The article gives values of normal and shear stresses acting at the study domain boundaries from the side of the material. |
