The effects of multi-scale particle shape characteristics on the small-strain stiffness of
granular soils remain controversial. This study revisits this topic using well-calibrated three …

This paper presents a numerical investigation about the effect of particle shape on small
strain properties (eg, shear stiffness and Poisson's ratio) of granular soils through 3D …

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 roughness of fractures may play an important role in affecting the migration and
placement of proppants during hydraulic fracturing operations. A series of proppant flow …

Scale effects and the influence of surface roughness were investigated on the contact
behavior of glass specimens of the grain-grain, grain-block and block-block configurations …

The effects of particle shape (angularity α and sphericity S), physical properties (shear
modulus G p and Poisson's ratio ν p) and particle size distribution (uniformity coefficient C u) …

Calcareous gravelly sand (CGS) is the primary building material used in the foundation
filling of island-reefs in the South China Sea. In this study, multiple consolidation-drained …

We present a barrier method for treating frictional contact on interfaces embedded in finite
elements. The barrier treatment has several attractive features, including:(i) it does not …

A modeling method for the particle-based flexible membrane boundary for the
drained/undrained triaxial test is proposed herein. First, the particle placement manner to …

The behavior of a sand-steel interface can be different than the shearing behavior of a sand.
This study focuses on the effect of shear loading on a sand-to-sand and a sand-steel …
