The contact overlap algorithms and contact models of both polyhedron-polyhedron and
polyhedron-boundary contact in discrete element method (DEM) has been proposed. The …

Calibration remains an important challenge in the estimation of discrete element
parameters. Importantly, the usability of the discrete element method (DEM) is directly …

The need for a detailed description of dense granular flows arises in several practical
applications. A continuum approach, where the solid phase is treated as a continuum, is …

The use of the Discrete Element Method to model engineering structures implementing
granular materials has proven to be an efficient method to response under various …

Granular flows through converging sections such as conical hoppers have been reported to
be submitted to instationarities, which in certain circumstances can appear to be organized …

The purpose of this paper is to present a methodology for obtaining granular models from a
GPU parallel implementation of the geometric separation particle packing strategy. This …

Railroads all around Europe and the world frequently employ ballast. To this day, ballasted
tracks are still largely the result of empirical design. Both maintenance practices, such as …

Granular flows through converging sections such as conical hoppers have been reported to
be submitted to instationarities, which in certain circumstances can appear to be organized …

Granular materials are ubiquitous in everyday life, in nature as well as in industry; therefore
the prediction of granular fluid dynamics is of great interest in both physics and engineering …

Le traitement, le transport, la maniabilité et le stockage des matériaux granulaires sont à
l'origine de nombreuses opérations industrielles. Il est donc essentiel de prévoir de manière …
