Spatiotemporal Hierarchy of Slow Avalanches During Creep
Vladimir Yu. Rudyak, Dor Shohat, Yoav Lahini
Far from equilibrium, amorphous solids exhibit structural relaxations that span a vast range of timescales such as physical aging and creep. Recently, it has been shown that such r…
Aging of amorphous materials under cyclic strain
Dor Shohat, Paul Baconnier, Itamar Procaccia +2
Amorphous materials driven away from equilibrium display a diverse repertoire of complex, history-dependent behaviors. One striking feature is a failure to return to equilibrium af…
Geometric control and memory in networks of hysteretic elements
Dor Shohat, Martin van Hecke
The response of driven frustrated media stems from interacting hysteretic elements. We derive explicit mappings from networks of hysteretic springs to their abstract representation…
Microscopic description of the intermittent dynamics driving logarithmic creep
Daniel J. Korchinski, Dor Shohat, Yoav Lahini +1
Disordered materials under an imposed forcing can display creep and aging effects, accompanied by intermittent, spatially heterogeneous dynamics. We propose a unifying microscopic…
Are crumpled sheets marginally stable?
Dor Shohat, Yoav Lahini, Daniel Hexner
We study networks of coupled bistable elastic elements, recently proposed as a model for crumpled thin sheets. The networks are poised on the verge of a localized instability, and…
