Depinning transition of dislocation assemblies: pileup and low-angle grain boundary
Paolo Moretti, M. -Carmen Miguel, Michael Zaiser +1
We investigate the depinning transition occurring in dislocation assemblies. In particular, we consider the cases of regularly spaced pileups and low angle grain boundaries interac…
Growth of a vortex polycrystal in type II superconductors
Paolo Moretti, M. -Carmen Miguel, Michael Zaiser +1
We discuss the formation of a vortex polycrystal in type II superconductors from the competition between pinning and elastic forces. We compute the elastic energy of a deformed gra…
Dislocation avalanche correlations
Jerome Weiss, M. -Carmen Miguel
Recently, mechanical tests on ice as well as dislocation dynamics simulations have revealed that plastic flow displays a scale-free intermittent dynamics characterized by dislocati…
Deblocking of interacting particle assemblies: from pinning to jamming
M. -Carmen Miguel, Jose S. Andrade, Stefano Zapperi
A wide variety of interacting particle assemblies driven by an external force are characterized by a transition between a blocked and a moving phase. The origin of this deblocking…
