Some important aspects of modelling clay platelet interactions using DEM (2021)
Journal Article
de Bono, J. P., & McDowell, G. R. (2022). Some important aspects of modelling clay platelet interactions using DEM. Powder Technology, 398, Article 117056. https://doi.org/10.1016/j.powtec.2021.117056

The discrete element method (DEM) is a popular tool for simulating soils, however it has rarely been used for modelling clays. This is despite the behaviour of clays being much less well understood compared to sands. This paper aims to increase the u...
