The jamming scenario - an introduction and outlook
Andrea J. Liu, Sidney R. Nagel, Wim van Saarloos +1
The jamming scenario of disordered media, formulated about 10 years ago, has in recent years been advanced by analyzing model systems of granular media. This has led to various new…
Low-frequency vibrations of soft colloidal glasses
Ke Chen, Wouter G. Ellenbroek, Zexin Zhang +8
We conduct experiments on two-dimensional packings of colloidal thermosensitive hydrogel particles whose packing fraction can be tuned above the jamming transition by varying the t…
Polymer rheology simulations at the meso- and macroscopic scale
Eric Sultan, Jan-Willem Van De Meent, Ellak Somfai +2
We show that simulations of polymer rheology at a fluctuating mesoscopic scale and at the macroscopic scale where flow instabilities occur can be achieved at the same time with dis…
Model for the Scaling of Stresses and Fluctuations in Flows near Jamming
Brian P. Tighe, Erik Woldhuis, Joris J. C. Remmers +2
We probe flows of soft, viscous spheres near the jamming point, which acts as a critical point for static soft spheres. Starting from energy considerations, we find nontrivial scal…
Local Coulomb versus Global Failure Criterion for Granular Packings
Silke Henkes, Carolina Brito, Olivier Dauchot +1
Contacts at the Coulomb threshold are unstable to tangential perturbations and thus contribute to failure at the microscopic level. How is such a local property related to global f…
Local contact numbers in two dimensional packings of frictional disks
Silke Henkes, Kostya Shundyak, Wim van Saarloos +1
We analyze the local structure of two dimensional packings of frictional disks numerically. We focus on the fractions x_i of particles that are in contact with i neighbors, and sys…
