On the Apparent Yield Stress in Non-Brownian Magnetorheological Fluids
Daniel Vagberg, Brian P. Tighe
We use simulations to probe the flow properties of dense two-dimensional magnetorheological fluids. Prior results from both experiments and simulations report that the shear stress…
Shear banding, discontinuous shear thickening, and rheological phase transitions in athermally sheared frictionless disks
Daniel Vågberg, Peter Olsson, S. Teitel
We report on numerical simulations of simple models of athermal, bidisperse, soft-core, massive disks in two dimensions, as a function of packing fraction , inelasticity of coll…
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…
Critical Scaling of Bagnold Rheology at the Jamming Transition of Frictionless Two Dimensional Disks
Daniel Vagberg, Peter Olsson, S. Teitel
We carry out constant volume simulations of steady-state, shear driven, rheology in a simple model of bidisperse, soft-core, frictionless disks in two dimensions, using a dissipati…
Correlations of plasticity in sheared glasses
Fathollah Varnik, Suvendu Mandal, Vijaykumar Chikkadi +5
In a recent paper [S. Mandal et al., Phys. Rev. E 88, 022129 (2013)] the nature of spatial correlations of plasticity in hard sphere glasses was addressed both via computer simulat…
Universality of Jamming Criticality in Overdamped Shear-Driven Frictionless Disks
Daniel Vågberg, Peter Olsson, S. Teitel
We investigate the criticality of the jamming transition for overdamped shear-driven frictionless disks in two dimensions for two different models of energy dissipation: (i) Durian…
Pressure Distribution and Critical Exponent in Statically Jammed and Shear-Driven Frictionless Disks
Daniel Vagberg, Yegang Wu, Peter Olsson +1
We numerically study the distributions of global pressure that are found in ensembles of statically jammed and quasistatically sheared systems of bidisperse, frictionless, disks at…
Dissipation and Rheology of Sheared Soft-Core Frictionless Disks
Daniel Vågberg, Peter Olsson, S. Teitel
We use numerical simulations to investigate the effect of different dissipative models on the shearing rheology of massive soft-core frictionless disks in two dimensions. We show t…
Finite-Size-Scaling at the Jamming Transition: Corrections to Scaling and the Correlation Length Critical Exponent
Daniel Vagberg, Daniel Valdez-Balderas, M. A. Moore +2
We carry out a finite size scaling analysis of the jamming transition in frictionless bi-disperse soft core disks in two dimensions. We consider two different jamming protocols: (i…
Glassiness, Rigidity and Jamming of Frictionless Soft Core Disks
Daniel Vågberg, Peter Olsson, S. Teitel
The jamming of bi-disperse soft core disks is considered, using a variety of different protocols to produce the jammed state. In agreement with other works, we find that cooling an…
