Shear thickening is the increase of the apparent viscosity as shear rate or shear stress
increases. This phenomenon is pronounced in concentrated (dense) suspensions of both …

The formation of cracks and emergence of shearing planes and other modes of rapid
macroscopic failure in geologic granular media involve numerous grain scale mechanical …

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) …

Particle-based simulations of discontinuous shear thickening (DST) and shear jamming (SJ)
suspensions are used to study the role of stress-activated constraints, with an emphasis on …

Understanding the extent to which discrete element method (DEM) simulations can capture
the critical state characteristics of granular materials is important to legitimize the use of DEM …

A comprehensive comparison between the Hertz–Mindlin model and the linear spring model
in true triaxial shear simulations of granular soils was conducted using the discrete-element …

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 …

By means of contact dynamic simulations, we investigate the contact network topology and
force chains in two-dimensional packings of elongated particles subjected to biaxial …

Using contact dynamics simulations, we compare the effect of rolling resistance at the
contacts in granular systems composed of disks with the effect of angularity in granular …

Abstract Models that introduce rolling resistance at the contact are widely employed in
simulations using the discrete element method (DEM) to indirectly represent particle shape …
