A particle-scale analysis of unload-reload hysteresis for normally consolidated kaolin (2023)
Journal Article
de Bono, J., & McDowell, G. (2023). A particle-scale analysis of unload-reload hysteresis for normally consolidated kaolin. Applied Clay Science, 246, Article 107190. https://doi.org/10.1016/j.clay.2023.107190

The mechanical behaviour of sands and clays subject to “normal” (plastic) compression are very similar, albeit at different stress levels, despite the differences in inter-particle interactions (Hertzian normal contact forces or similar for sand) and...

DEM study of an “avatar” railway ballast with real particle shape, fabric and contact mechanics (2023)
Journal Article
Tolomeo, M., & McDowell, G. R. (2023). DEM study of an “avatar” railway ballast with real particle shape, fabric and contact mechanics. Granular Matter, 25(2), Article 32. https://doi.org/10.1007/s10035-023-01322-1

In this paper we show DEM simulations of static and cyclic large triaxial tests on a sample of railway ballast. The sample is reconstructed from X-Ray tomography images of an untested laboratory sample, recovered by impregnation with an epoxy resin....
