Measurements of the Yield Stress in Frictionless Granular Systems
Ning Xu, Corey S. O'Hern
We perform extensive molecular dynamics simulations of 2D frictionless granular materials to determine whether these systems can be characterized by a single static yield shear str…

Stabilization of nonlinear velocity profiles in athermal systems undergoing planar shear flow
Ning Xu, Corey S. O'Hern, Lou Kondic
We perform molecular dynamics simulations of model granular systems undergoing boundary-driven planar shear flow in two spatial dimensions with the goal of developing a more comple…

Random close packing revisited: How many ways can we pack frictionless disks?
Ning Xu, Jerzy Blawzdziewicz, Corey S. O'Hern
We create collectively jammed (CJ) packings of 50-50 bidisperse mixtures of smooth disks in 2d using an algorithm in which we successively compress or expand soft particles and min…
