Present experiments and computational simulations furnish a fundamental background to
the understanding of plastic flow across sample sizes. It is shown that self-organized …

The existence of a well-defined yield stress, where a macroscopic crystal begins to
plastically flow, has been a basic observation in materials science. In contrast with …

This review examines the recent literature that has focused on uniaxial compression
experiments of single crystals at the micrometer scale. Collectively, the studies discovered …

Recent experimental observations revealed the inherent nature of strong intermittent and
heterogeneous plastic deformation at the nano-to micrometer scale. We present here a …

Stochastic, discontinuous flow is ubiquitous in the plastic deformation of small-volume
metallic materials. We have identified a size-strengthening effect on the stress to initiate the …

Mechanism-based discrete dislocation plasticity is used to investigate the effect of size on
micron scale crystal plasticity under conditions of macroscopically homogeneous …

Nanoindentation techniques recently developed to measure the mechanical response of
crystals under external loading conditions reveal new phenomena upon decreasing sample …

In small dimensions, the flow stress of metallic samples shows a size-dependence such that
smaller is stronger, even in nominally strain gradient-free loading conditions. However, the …

We report direct measurements of displacement jump velocities in deforming nano-and
microcrystals. These velocities exhibit large scatter and no correlation with plastic strain …

Directly tracing the spatiotemporal dynamics of intermittent plasticity at the micro‐and
nanoscale reveals that the obtained slip dynamics are independent of applied stress over a …
