Constraint-based approach to granular dispersion rheology
We present a phenomenological model for granular suspension rheology in which particle
interactions enter as constraints to relative particle motion. By considering constraints that …

A fast adhesive discrete element method for random packings of fine particles
Introducing a reduced particle stiffness in discrete element method (DEM) allows for bigger
time steps and therefore fewer total iterations in a simulation. Although this approach works …

Granular packings with sliding, rolling, and twisting friction
Intuition tells us that a rolling or spinning sphere will eventually stop due to the presence of
friction and other dissipative interactions. The resistance to rolling and spinning or twisting …

Colloidal gelation with non-sticky particles
Colloidal gels are widely applied in industry due to their rheological character—no flow
takes place below the yield stress. Such property enables gels to maintain uniform …
