-core analysis of shear-thickening suspensions
Omer Sedes, Bulbul Chakraborty, Hernan A. Makse +1
Shear thickening of suspensions is studied by discrete-particle simulation, accounting for hydrodynamic, repulsive, and contact forces. The contact forces, including friction, are…
The jamming transition is a k-core percolation transition
Flaviano Morone, Kate Burleson-Lesser, H. A. Vinutha +2
We explain the structural origin of the jamming transition in jammed matter as the sudden appearance of k-cores at precise coordination numbers which are related not to the isostat…
High-resolution of particle contacts via fluorophore exclusion in deep-imaging of jammed colloidal packings
Eru Kyeyune-Nyombi, Flaviano Morone, Wenwei Liu +3
Understanding the structural properties of random packings of jammed colloids requires an unprecedented high-resolution determination of the contact network providing mechanical st…
Equation of state for random sphere packing with arbitrary adhesion and friction
Wenwei Liu, Yuliang Jin, Sheng Chen +2
We systematically generate a large set of random micro-particle packings over a wide range of adhesion and friction by means of adhesive contact dynamics simulation. The ensemble o…
Edwards Statistical Mechanics for Jammed Granular Matter
Adrian Baule, Flaviano Morone, Hans J. Herrmann +1
In 1989, Sir Sam Edwards made the visionary proposition to treat jammed granular materials using a volume ensemble of equiprobable jammed states in analogy to thermal equilibrium s…
Effect of long-range repulsive Coulomb interactions on packing structure of adhesive particles
Sheng Chen, Shuiqing Li, Wenwei Liu +1
The packing of charged micron-sized particles was investigated using discrete element simulations based on adhesive contact dynamic model. The formation process and the final obtai…
