Establishing a mesoscale model of asphalt concrete is significantly challenging due to its
inherent heterogeneity and high proportion of aggregates. Initially, a novel approach for …

Many field observations show that the shape characteristic of particles constituting natural or
industrial loose deposits is often size-correlated, that is, either more regular or irregular for …

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 …

The multi-scale characteristics of particle morphology, including the overall form, local
roundness and surface roughness, affect the critical state behavior of sands and should be …

Acquiring particle shapes from raw particle images with complex backgrounds is a
prerequisite for particle shape evaluation, yet it is a challenging task. In this study, a …

Particle shape in granular materials exhibits both polydisperse and multi-level
characteristics, which are intrinsically linked to the mechanical behaviours of granular …

Particle shape affects the mechanical properties of sands, but the underlying micro-
mechanisms are not yet explored, at least partially, due to difficulties in accessing the …

We propose an enhanced tool by combining X-ray micro-computed tomography test and
hybrid finite and discrete element method to investigate the mechanical behaviors of …
