Clay micromechanics: Mapping the future of particle-scale modelling of clay [PDF]
E3S Web of ConferencesGeotechnical engineers need to predict the macroscopic behaviour of clays in terms of strength, stiffness, and permeability and the variation in these properties during deformation. Engineers also need to predict the influence of environmental variables (

3‐D impulse‐based level‐set method for granular flow modeling
International Journal for Numerical Methods in Engineering, Volume 125, Issue 17, 15 September 2024.Abstract We explore the viability of modeling dynamic problems with a new formulation of an impulse‐based Level‐Set DEM (LS‐DEM). The new formulation is stable, fast, and energy conservative. However, it can be numerically stiff when the assembly has substantial mass differences between particles.

International Journal for Numerical Methods in Engineering, Volume 125, Issue 5, 15 March 2024.Abstract The level‐set‐discrete‐element‐method (LS‐DEM) was developed to overcome the shape limitation of traditional discrete element method. LS‐DEM's shape generality relies on a node‐based surface discretization of grain boundary, and it has been used to shed new light of a variety of granular mechanics applications with realistically shaped grains ...

On the friction dependency of the stress Lode angle
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 48, Issue 4, Page 1001-1017, March 2024.Abstract The shape of the failure locus of a material is significant for its strength predictions. Even when constitutive models include the same critical stress surface, different critical stress ratios can be predicted for an identical applied isochoric strain path. In this article, we investigate critical stress predictions of different constitutive

Comparing RUSLE LS Calculation Methods Across Varying DEM Resolutions
Modern GeográfiaSoil erosion reduces land productivity and causes environmental degradation. Soil erosion models, such as the Revised Universal Soil Loss Equation (RUSLE), are used to estimate the severity and distribution of erosion.

Elevation-Dependent Removal of Cirrus Clouds in Satellite Imagery
Remote Sensing, 2020 Masking of cirrus clouds in optical satellite imagery is an important step in automated processing chains. Firstly, it is a prerequisite to a subsequent removal of cirrus effects, and secondly, it affects the atmospheric correction, i.e., aerosol and ...
