Scale-free intermittent flow in crystal plasticity
Under stress, crystals irreversibly deform through complex dislocation processes that
intermittently change the microscopic material shape through isolated slip events. These …

Scale invariance in plastic flow of crystalline solids
M Zaiser - Advances in physics, 2006 - Taylor & Francis
From the traditional viewpoint of continuum plasticity, plastic deformation of crystalline solids
is, at least in the absence of so-called plastic instabilities, envisaged as a smooth and quasi …

Statistics of dislocation slip avalanches in nanosized single crystals show tuned critical behavior predicted by a simple mean field model
We show that slowly sheared metallic nanocrystals deform via discrete strain bursts (slips),
whose size distributions follow power laws with stress-dependent cutoffs. We show for the …

Athermal mechanisms of size-dependent crystal flow gleaned from three-dimensional discrete dislocation simulations
Recent experimental studies have revealed that micrometer-scale face-centered cubic (fcc)
crystals show strong strengthening effects, even at high initial dislocation densities. We use …

Avalanches and plastic flow in crystal plasticity: an overview
Crystal plasticity is mediated through dislocations, which form knotted configurations in a
complex energy landscape. Once they disentangle and move, they may also be impeded by …
