Full understanding of the compression and permeability behaviors of weakly anisotropic
sandstones is a major challenge. The present work aims to address this challenging task …

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 …

This research presents a new heterogeneity index to describe micro-geometric
heterogeneity induced by grain size variation in intact rock. Micro-geometric heterogeneity is …

Interfacial seepage on soil-structure interface is common in water-related engineering, such
as dam, culvert, water tunnel, foundation pit, etc. As a weak part in the project, seepage …

We present a numerical analysis on injection-induced crack propagation and coalescence
in brittle rock. The DEM network coupling model in PFC is modified to capture the evolution …

A simulation framework combining the coupling fluid method (CFM) and flexible coupling
boundary method was developed to simulate drained and undrained triaxial tests. The …

Grain scale tests can provide useful information about geological materials interface
properties and to understand the possible role of geological environments on their behavior …

This paper presents a numerical investigation using the three-dimensional discrete element
method (DEM) to evaluate the macro-scale properties of saturated silt in a cyclic triaxial test …

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 …

This research presents a grain-based stress corrosion model to simulate time-dependent
failure of brittle rock. Time-dependent deformation of rock is considered as the manifestation …
