A fundamental understanding of the underlying physics of granular (particulate) systems is
not only of academic interest, but is also highly relevant for industrial applications …

The discrete element method (DEM) is widely used to model a range of processes across
many industries. This paper reviews current DEM models for several common …

Granular materials in industrial applications or nature usually consist of a wide variety of
differently formed particles. Very often the shape of the involved objects does not even …

The need to understand and predict the long-and short term behavior of railway ballast calls
for extensive experimental programs as well as the development of reliable numerical …

Adequacy of approximation of ellipsoidal particles composed of a set of sub-spheres for
numerical Discrete Element Method (DEM) simulations is examined. The algorithm of …

This paper reviews the state-of-the-art contact force models for non-spherical particles,
which describe the relationship between the contact force and the geometrical, material, and …

In this paper a multi-sphere as well as a polyhedral approach is investigated as method of
shape-approximation within the discrete element method. The two approaches are …

Tablet coating is a common pharmaceutical technique of applying a thin polymer-based film
to a tablet or a granule containing active pharmaceutical ingredients (APIs). Inter-and intra …

A discrete element model based on super-ellipsoids was used to simulate cylindrical particle
flow. The model can describe a cylindrical particle accurately provided the shape indices of …

The properties of granular materials depend strongly on the shapes of their individual
constituent particles or granules. Nonetheless, incorporating the effects of non-spherical or …
