Microscopic mechanical properties of rockfill materials under different stress paths Granular Matter (IF 2.4) Pub Date : 2024-03-11
Abstract The mechanical properties of rockfill materials are not only influenced by microscopic factors such as particle morphology and gradation, but also closely related to different loading stress paths. It is of great significance to study the microscopic mechanical properties of rockfill materials under different stress paths for revealing the macroscopic mechanical properties as well as the microscopic

An inclusion model for predicting granular elasticity incorporating force chain mechanics Granular Matter (IF 2.4) Pub Date : 2024-03-10
Abstract Granular media is ubiquitous, playing a vital role in a diverse set of applications. The complex microstructure of granular media results from assorted particle shapes, morphologies, and packings, make it difficult to predict its macroscopic behavior. Under compression, these complex microstructures enable highly anisotropic and heterogenous behaviors, including creation of highly-loaded particles

Influence of gradation range on strong contact network in granular materials Granular Matter (IF 2.4) Pub Date : 2024-03-06
Abstract The topology of the granular material in the microscale affects the macroscale mechanical responses. Based on graph theory, the particles can be considered as nodes, and contacts can be considered as links, which form the contact network. Within the contact network, different force thresholds are applied to distinguish the strong and weak networks. This paper focuses on the influence of gradation

Shear characteristics of granular materials with different friction coefficients based on ring shear test Granular Matter (IF 2.4) Pub Date : 2024-02-06
Abstract Interparticle friction is an intrinsic property of particles, which plays an important role in the macroscopic and microscopic shear mechanical properties of granular materials. In this research, we investigate the shear behavior of granular materials with different friction coefficients using ring shear tests. The particle image velocimetry (PIV) technique was also used to analyze the shear

Fragmentation model integrated in a gravity flow simulator for block caving planning Granular Matter (IF 2.4) Pub Date : 2024-01-20
Abstract Rock fragment size is a key variable in several mining stages such as underground mine design, equipment selection, and mineral processing. In Block Caving, rock fragment sizes are affected by fragmentation during gravity flow in the ore column while ore is being extracted from drawpoints. Additionally, smaller fragments can percolate between large fragments during gravity flow. These two

Continuum modelling of a just-saturated inertial column collapse: capturing fluid-particle interaction Granular Matter (IF 2.4) Pub Date : 2024-01-19
Abstract This work presents a simple two-phase flow model to analyse a series of axisymmetric granular column collapse tests conducted under elevated gravitational accelerations. These columns were prepared with a just-saturated condition, where the granular pores were filled with a Newtonian fluid up to the column’s free surface. In this configuration, unlike the fully submerged case, air-water-grain

Abstract The repose of granular materials is investigated via two different Discrete Element Method (DEM) implementations in comparison with an experimental reference from a recently proposed benchmark setup. On a methodological standpoint, a rigorous measurement method of the angle of repose (AOR) is first proposed for plane-strain and axisymmetric conditions as encountered in the reference experiments

Energy transport and dissipation in granular systems Granular Matter (IF 2.4) Pub Date : 2023-07-29 Kostas Senetakis
The study of energy transport in granular systems can involve a number of different angles to view the problem; for example, one can propagate sinusoidal waves within the granular assembly, which makes the particles vibrate; besides the large wavelength low-amplitude elastic limit, this can be at very large frequencies and medium-large amplitudes, thereby posing the particles in perturbations of different
