DOI: 10.1007/s40571-017-0160-9
Abstract: Numerical simulation of granular systems is often based on a discrete element method. The nonsmooth contact dynamics approach can be used to solve a broad range of granular problems, especially involving rigid bodies. However, difficulties… read more here.

DOI: 10.1016/j.apt.2019.12.002
Abstract: Abstract Under continual disturbance such as vibration, tumbling, flow or aeration, granular or powder systems can display solid or fluid like behavior. Using a well-mixed system of same size (0.2 mm) non-cohesive glass beads and iron… read more here.

DOI: 10.1103/physrevlett.129.228004
Abstract: Using particle trajectory data obtained from x-ray tomography, we determine two kinds of effective temperatures in a cyclically sheared granular system. The first one is obtained from the fluctuation-dissipation theorem which relates the diffusion and… read more here.
