Numerical simulations of dense granular systems with and without cohesive effects
… to repulsive and possibly attractive interaction forces. These interactions that may be history dependent, make the systems that consist of a large number of particles complex to analyze and difficult to understand using analytical methods. For this reason, most of the work in the field of …

Photoelastic study of dense granular free-surface flow rheology and size segregation
… of original experiments where instantaneous forces between individual particles within the bulk of 2D flows are quantified. The specific type of granular flow we study is gravity-driven, dry, and in the slow to intermediate regime. Here we describe a novel adaptation of the photoelastic …

Understanding bulk behavior of particulate materials from particle scale simulations
… of packing to various degrees. The heterogeneous force networks within particle assembly under external compressive loading are investigated as well. The results show that coarse-coarse contacts dominate the strong network and coarse-fine contacts dominate the total network. Next, DEM models are …
