Granular materials are the most recurrent form of solid-state matter on Earth. They challenge
researchers and engineers in various fields not only because they occur with a broad variety …

The emergence of the discrete element method (DEM) provides a powerful tool to
investigate the macro–micro mechanism of soil-structure interface (SSI). Understanding the …

This paper presents a micro-mechanical study on the characteristics of shear-induced
anisotropy in granular media. Based on three-dimensional Discrete Element Method (DEM) …

A numerical investigation of particle shape effects on fabric of granular packing is carried out
using the three dimensional discrete element method with a superellipsoid model. A broad …

This paper presents a novel method to generate realistic packings for discrete modelling of
granular materials. To generate a packing of 2D dense sample in a container of arbitrary …

When velocity jumps are occurring, the dynamics is said to be nonsmooth. For instance, in
collections of contacting rigid bodies, jumps are caused by shocks and dry friction. Without …

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 …

Particle shape has been regarded as a key factor affecting mechanical behaviors of granular
assemblies. The present work proposes a shape descriptor, ie, asphericity, to isolate the …

We present a systematic numerical investigation of the shear strength and structure of
granular packings composed of irregular polyhedral particles. The angularity of the particles …

The rheological behavior of non-cohesive soils results from the arrangement and complex
geometry of the grains. Numerical models based on discrete element modeling provides an …
