While simulation of the drained true triaxial response of particulate assemblies using
discrete element method (DEM) has caught the attention of researchers in the recent years …

The discrete element method (DEM) is applied to investigate instability of frictional
particulate assemblies sheared under the triaxial constant shear drained (CSD) condition …

Failures by divergence instabilities in rate-independent non-associated material, such as
granular matter, can occur from mechanical states described by the plastic stress limit …

Granular materials react under external loading by self-organizing the topology of the grain
assembly. Thus, quasi-linear grain patterns, known as force chains, develop within the …

Within the framework of the second‐order work theory, the onset of instabilities is explored
numerically in loose granular materials through three‐dimensional DEM simulations. Stress …

In recent years, binary mixtures have been the subject of numerous experimental and
numerical studies. However, few attempts have been made on investigating the effect of …

Diffuse instability is a typical failure mode of sand that occurs before the perfect plastic flow
condition is attained. Whereas extensive laboratory experiments have demonstrated the …

The failure mechanism and limit support pressure are essential factors for the stability
assessment of tunnel face during shield tunneling. Previous studies were mostly based on …

Lateral stress relief and effective stress reduction have been recognised as the culprits in
flow failures of several mine tailings dams. This research examines the instability of coarse …

This paper examines instabilities in granular materials from a microscopic point of view
through numerical simulations conducted using a discrete element method on two three …
