DEM simulations of soil creep due to particle crushing [PDF]

Géotechnique, 2013
One mechanism that may contribute to creep in sand is that heavily loaded grains may progressively crush, following the growth of microcracks due to hydrolysis at crack tips. Weibull's statistical model of brittle failure can accommodate these time effects.

Triaxial compression tests on a crushable sand in dry and wet conditions [PDF]

, 2015
A calcareous sand from the Persian Gulf is subjected to a series of dry and fully drained saturated triaxial shear tests. The samples are prepared at relative densities of 65% and either left dry or saturated. They are consolidated to confining pressures

Amphibole: A major carrier of helium isotopes in crustal rocks [PDF]

, 2016
The first evidence for a specific role of amphiboles in He isotope balance of crustal rocks was presented in early contributions by Gerling et al. (1971, 1976).

One-dimensional dynamic compressive behavior of dry calcareous sand at high strain rates

Journal of Rock Mechanics and Geotechnical Engineering, 2019
Calcareous sand has distinct characteristics in comparison with silica sand, such as dynamic behavior at high strain rates (HSRs). This is closely related to pile driving, aircraft wheel loading and mining activities.

Particle shape effects on particle size measurement for crushed waste glass [PDF]

Advanced Powder Technology, 2017
Abstract Recently, narrow particle size distributions, as measured by sieve analysis, of crushed waste glass were used as a replacement for Portland cement in concrete. Their chemical reactivity was successfully studied as a function of this measure of particle size.

Investigation of the particle crushing characteristics of stacked stone materials under different stress path conditions

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Stone fill materials are widely used in engineering projects such as earth-rock dams, railways, and highway embankments. Nevertheless, they are susceptible to particle breakage, which can lead to a decline in engineering performance.

Influence of real particle morphology on single particle crushing behavior of rockfill based on FDEM

Journal of Rock Mechanics and Geotechnical Engineering
Particle morphology is critical in affecting the crushing behavior of rockfill materials. In contrast, most current single particle simulations lack satisfactory morphology accuracy, and the resulting crushing modes deviate from observations to some ...

One-dimensional compression of a crushable sand in dry and wet conditions [PDF]

, 2015
This paper presents the results of a series of dry and wet one-dimenional compression tests on a calcareous sand from the Persian Gulf. Calcareous grains crush more easily compared to silica grains, a fact that is mainly attributed to their angular shape

DEM of triaxial tests on crushable sand [PDF]

, 2014
This paper presents simulations of high-pressure triaxial shear tests on a crushable sand. The discrete element method is used, featuring a large number of particles and avoiding the use of agglomerates.
