Granular soils are abundant in nature and extensively used for engineering purposes.
Understanding the correlation between particle breakage and its mechanical response of …

The rolling resistance model has been employed in the discrete element modelling in
geomechanics, as an alternative computationally efficient approach to capture the …

Particle morphology plays a key role in affecting physical and mechanical behaviors of
granular media. While various mathematical approaches and shape descriptors have been …

Gap-graded granular soils have a wider grain size distribution and more heterogeneous
fabric structure than normal soils. It is critical to choose the sample size of element tests in a …

This paper presents a novel framework for the discrete modeling of the large-scale triaxial
test of rock clasts, considering both the realistic particle shapes and veritable flexible …

A comprehensive comparison between the Hertz–Mindlin model and the linear spring model
in true triaxial shear simulations of granular soils was conducted using the discrete-element …

In this work, we numerically investigate the quasi-static shear behavior of ellipsoids under
triaxial compression using the level set discrete element method (LS-DEM). Assemblies …

This paper presents a signed distance field (SDF) approach for unified discrete element
method (DEM) modeling of granular media using arbitrarily shaped particles. The SDF …

This report investigated the effects of irregular particles on macroscopic and microscopic
behaviour under triaxial compression tests for a range of various roundnesses. A multi …

This study aims to numerically investigate the dependence of shear behaviors of granular
materials on particle multi-level morphology, encompassing form (mean of elongation and …
