With the rapid development of human lunar exploration projects, the lunar base
establishment and resource utilization are on the way, and hence it is urgent and significant …

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) …

The concept of the critical state in granular soils needs to make proper reference to the fabric
structure that develops at critical state. This study identifies a unique property associated …

This paper presents a review of the physics controlling various forces between clay particles,
and the incorporation of these forces in a DEM contact model in PFC 3D. This contact model …

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 series of micro-mechanical tests was carried out in order to investigate the inter-particle
coefficient of friction at the contacts of quartz minerals of Leighton Buzzard sand. For this …

Previous studies on the hollow cylinder torsional shear test (HCTST) have mainly focused
on the macroscopic behavior, while the micromechanical responses in soil specimens with …

The inter-particle contact evolution of two sheared granular materials, ie, a spherical glass
bead (GB) specimen and an angular Leighton Buzzard Sand (LBS) specimen, is …

Mixtures of sand and rubber particles were simulated using DEM. Rubber content varied
from 0% to 50%. The numerical samples were sheared in the range of 10− 5–10− 2% of ε 1 …

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 …
