The arrangements of particles and forces in granular materials have a complex organization
on multiple spatial scales that range from local structures to mesoscale and system-wide …

Shear thickening of suspensions is studied by discrete-particle simulation, accounting for
hydrodynamic, repulsive, and contact forces. The contact forces, including friction, are …

Dense suspensions are a prototype of fluid that can dynamically enhance their viscosity to
resist strong forcing. Recent work established that the key to a large viscosity increase …

In composite materials composed of a soft polymer matrix and rigid, high aspect-ratio
particles, the composite undergoes a transition in mechanical strength when the …

Suspensions are mixtures of solid particles in a liquid medium. As the volume fraction of the
suspending particles approaches the maximal jamming packing fraction, ϕ J, the material …

Shear thickening is a rheological behavior observed in dense suspensions where the
viscosity increases with the shear rate, and in the scenario of discontinuous shear thickening …
