Rheological instability in a simple shear thickening model
D. A. Head, A. Ajdari, M. E. Cates
We study the strain response to steady imposed stress in a spatially homogeneous, scalar model for shear thickening, in which the local rate of yielding Γ(l) of mesoscopic `elastic…

Robust propagation direction of stresses in a minimal granular packing
D. A. Head, A. V. Tkachenko, T. A. Witten
By employing the adaptive network simulation method, we demonstrate that the ensemble-averaged stress caused by a local force for packings of frictionless rigid beads is concentrat…
