Granular materials, like sand, powder or grains present intriguing phenomena. Vibration and
shearing can lead to convective motion and segregation. A variation of stress may cause …

Flows of solid particles are known to exhibit a clustering instability—dynamic microstructures
characterized by a dense region of highly concentrated particles surrounded by a dilute …

The contacts between cohesive, frictional particles with sizes in the range 0.1–10 μm are the
subject of this study. Discrete element model (DEM) simulations rely on realistic contact …

For the simulation of dense granular systems the Discrete Element Method based on a soft-
sphere approach is commonly used. In such simulations collisions between particles take a …

A new computational fluid-dynamic (CFD) model with a separate granular temperature (2/3
random particle kinetic energy per unit of mass) equation for each phase or particle size was …

The contact dynamics (CD) method is presented as a discrete element method for the
simulation of nonsmooth granular dynamics at the scale of particle rearrangements where …

The discrete element method (DEM) in the simulation of static packings allows one to
investigate the behavior of granular materials by modeling the forces on the particle level …

The discrete modelling and understanding of the particle dynamics in fluidized bed
apparatuses, mixers, mills and others are based on the knowledge about the physical …

This paper presents a study on the rebound behaviour of spheres impacted normally against
a target wall using finite element methods. The emphasis is on the prediction of the …

In this paper, the energy dissipation during the normal impact of an elastic spherical particle
with a substrate, which is assumed to be elastic or elastic–plastic, is investigated using the …
