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 …

Despite the significant progresses in discrete-based numerical studies of granular materials,
most efforts have been placed in the study of large deformation problems and there are …

The critical-state response of granular assemblies composed of elastic spheres under
generalised three-dimensional loading conditions was investigated using the discrete …

Rock fracture and the induced displacement field are investigated through physical and
numerical experiments. A Berea sandstone specimen with a central notch was tested in …

Fabric anisotropy is a sought-after micro index to correlate macro mechanical responses of
granular materials. In this work, the discrete-element method is utilised to simulate multi …

Both the solid and fluid phases in a debris flow vitally influence the impact dynamics against
a rigid barrier. However, previous numerical and analytical models commonly adopt an …

The discrete element method (DEM) has been extensively used to capture the macroscopic
and particulate response of granular materials. Although particle rolling (ie controlled by …

The contact network of granular materials is often divided into strong and weak subnetworks,
which play different roles in micromechanics. Within the strong contact network, there exists …

This paper presents the effect of particle morphology (grain shape) on the mechanical
response of granular materials. Two model systems with extreme differences in morphology …

This paper presents CFD-DEM simulations of undrained true triaxial tests on a granular soil.
A CFDEM solver that considers compressible fluid and moving meshes has been developed …
