Abstract
Micron scale crystals deform very differently from macroscopic samples of the same materials. Their deformation is characterized by a size-dependent yield stress and intermittent plastic strain bursts. Here we demonstrate that size effects and strain bursts can be related to fundamental collective phenomena that govern the dynamics of dislocation systems on all scales. We confirm the theory by demonstrating agreement between the results of 2D and 3D dislocation dynamics simulations and experimental results on compressed micropillars.
