Modeling the mixing of cohesionless materials when the flow of granular medium occurs with plastic shear deformations

The mechanism responsible for interaction between inelastic spherical homogeneous particles during shearing of a granular medium subject to plastic deformation is analyzed; based on this analysis, a method is proposed for prediction of the coefficient of quasi-diffusion mixing as a function of particle size and flow characteristics.
The kinetics of particle mixing when materials are subject to plastic shear deformations are investigated by methods of physical and mathematical modeling; these investigations suggest the adequacy of the computational function proposed for determination of the coefficient of quasi-diffusion mixing.
