Effect of Collisional Elasticity on the Bagnold Rheology of Sheared Frictionless Two Dimensional Disks
Daniel Vågberg, Peter Olsson, S. Teitel
We carry out constant volume simulations of steady-state, shear driven flow in a simple model of athermal, bidisperse, soft-core, frictionless disks in two dimensions, using a diss…
Nonlocal elasticity near jamming
Karsten Baumgarten, Daniel Vagberg, Brian P. Tighe
We demonstrate that the elasticity of jammed solids is nonlocal. By forcing frictionless soft sphere packings at varying wavelength, we directly access their transverse and longitu…
Mapping the jamming transition of bidisperse mixtures
D. J. Koeze, D. Vågberg, B. B. T. Tjoa +1
We systematically map out the jamming transition of all 2D bidisperse mixtures of frictionless disks in the hard particle limit. The critical volume fraction, mean coordination num…
Beyond linear elasticity: Jammed solids at finite shear strain and rate
Julia Boschan, Daniel Vagberg, Ellak Somfai +1
The shear response of soft solids can be modeled with linear elasticity, provided the forcing is slow and weak. Both of these approximations must break down when the material loses…
