DOI: 10.1016/j.compgeo.2020.103732
Abstract: Abstract The behaviour of cemented granular material is complicated by the fact that the eventual cemented properties depend on the conditions under which cement hydration (curing) takes place. There are a number of situations in… read more here.

DOI: 10.1016/j.ijmecsci.2019.105313
Abstract: Abstract Granular materials, such as mineral products, soil and chemical fertilizer, normally contain unsaturated free moisture. This unsaturated moisture could migrate in the granular material and its processing, resulting in handling and safety concerns due… read more here.

DOI: 10.1016/j.powtec.2017.04.030
Abstract: Abstract The size of particle is a relevant parameter in the study of the granular material behaviour. For wet granular materials, it affects the capillary force and the number of liquid bridges. We present quantitative… read more here.

DOI: 10.1103/physreve.101.032904
Abstract: We present a simple method to prepare a granular material with a controlled cohesion between particles. The granular material is made of spherical glass beads coated with a polyborosiloxane polymer. This material is proved to… read more here.

DOI: 10.1103/physreve.102.012908
Abstract: Modeling collective motion in nonconservative systems, such as granular materials, is difficult since a general microscopic-to-macroscopic approach is not available: there is no Hamiltonian, no known stationary densities in phase space, and not a known… read more here.
