Armouring of a frictional interface by mechanical noise
Elisa El Sergany, Matthieu Wyart, Tom W. J. de Geus
A dry frictional interface loaded in shear often displays stick-slip. The amplitude of this cycle depends on the probability that a microscopic event nucleates a rupture and on the…
Stick-slip in a stack: how slip dissonance reveals aging
Samuel Poincloux, Pedro M. Reis, Tom W. J. de Geus
We perform physical and numerical experiments to study the stick-slip response of a stack of slabs in contact through dry frictional interfaces driven in quasistatic shear. The rat…
Scaling description of creep flow in amorphous solids
Marko Popović, Tom W. J. de Geus, Wencheng Ji +2
Amorphous solids such as coffee foam, toothpaste or mayonnaise display a transient creep flow when a stress is suddenly imposed. The associated strain rate is commonly found to…
Mean-field description for the architecture of low-energy excitations in glasses
Wencheng Ji, Tom W. J. de Geus, Elisabeth Agoritsas +1
In amorphous materials, groups of particles can rearrange locally into a new stable configuration. Such elementary excitations are key as they determine the response to external st…
Thermally activated flow in models of amorphous solids
Marko Popović, Tom W. J. de Geus, Wencheng Ji +1
Amorphous solids yield at a critical value of the imposed stress through a dynamical phase transition. While sharp in athermal systems, the presence of thermal fluctuatio…
