Understanding and modelling the dynamic behaviour of particulate systems has been a
major research focus worldwide for many years. Discrete particle simulation plays an …

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 …

A broad class of disordered materials including foams, glassy molecular systems, colloids
and granular materials can form jammed states. A jammed system can resist small stresses …

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 …

The rolling resistance model has been employed in the discrete element modelling in
geomechanics, as an alternative computationally efficient approach to capture the …

We examine the coevolution of N cycles and force chains as part of a broader study which is
designed to quantitatively characterize the role of the laterally supporting contact network to …

The discrete element method is a widely used particle orientated simulation approach for
modeling granular systems. It is based on tracking each particle's movement and its …

We present a numerical analysis of the effect of particle elongation on the quasistatic
behavior of sheared granular media by means of the contact dynamics method. The particle …

Force chain buckling, leading to unjamming and shear banding, is examined quantitatively
via a discrete element analysis of a two-dimensional, densely-packed, cohesionless …
