A numerical investigation of particle shape effects on fabric of granular packing is carried out
using the three dimensional discrete element method with a superellipsoid model. A broad …

The emergence of the discrete element method (DEM) provides a powerful tool to
investigate the macro–micro mechanism of soil-structure interface (SSI). Understanding the …

This paper is a review of the use of particulate discrete element modeling (DEM) in
geomechanics. The overall objective of the paper is to serve as an introduction to …

Particle shape has been regarded as a key factor affecting mechanical behaviors of granular
assemblies. The present work proposes a shape descriptor, ie, asphericity, to isolate the …

This paper investigated the effect of the particle angularity in light of its importance in
angular particle assemblies, using the discrete element method (DEM). A discrete element …

Rock aggregates are commonly used granular material in building engineering. The 3D
reconstruction of realistic rock aggregates is significant for the study of their mechanical …

In this study, the effects of particle sphericity and initial fabric on the shearing behavior of soil-
structural interface were analyzed by discrete element method (DEM). Three types of …

We explore the effect of particle shape on the angle of repose (AoR) in granular packing
using a three-dimensional discrete element method. Non-spherical particles were modeled …

Coarse aggregates are essential for constructing railways and highways, as they affect
structural performance through their compacted state and shear strength. Particle geometry …

The shear behavior at the interface between the soil and a structure is investigated at the
macroscale and particle‐scale levels using a 3‐dimensional discrete element method …
