Quantitative DEM of dense granular packings with a multiple contacts force model

Abstract

We present a new force model for performing quantitative simulations of dense granular materials. Interactions between multiple contacts on the same grain are explicitly taken into account. Our readily applicable method retains all the advantages of discrete simulations and does not require the use of costly finite elements. The new model accurately reproduces the experimental measurements we recently demonstrated, including contact force distributions in full 3D, at all compression levels up to the experimental maximum limit of 13%. Comparisons with the traditional non-deformable spheres approach is provided, as well as with alternative models for interactions between multiple contacts. The success of our model compared to these alternatives provides new insights for dense granular packings.
