A stochastic discrete slip approach is proposed to model plastic deformation in submicron
domains. The model is applied to the study of submicron pillar (D≤ 1 μ m) compression …

Plastic deformation of micro-and nanoscale samples differs from macroscopic plasticity in
two respects:(i) the flow stress of small samples depends on their size, and (ii) the scatter of …

Plastic flow in crystal at submicron-to-nanometer scales involves many new interesting
problems. In this paper, a unified computational model which directly combines 3D discrete …

Discrete dislocation dynamics simulations in three dimensions have been used to examine
the role of dislocation multiplication and mobility on the plasticity in small samples under …

In small-scale mechanical tests, such as micropillar compression tests, plastic deformation is
often localized in narrow slip traces. These slip traces result from a few dislocation sources …

Recent studies of micro-and nano-scale metallic structures have exposed considerable
statistical distribution, in addition to significant size dependencies, in the yield strength. This …

Systematic experimental investigations have demonstrated that the plastic deformation of
micropillar proceeds through a sequence of intermittent bursts, the sizes of which follow …

Micron-scale single-crystalline materials deform plastically via large intermittent strain bursts
that make the deformation process non-deterministic. Here we investigate this stochastic …

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 …

We present a computational study on the effects of sample size on the strength and plastic
flow characteristics of micropillars under compression loading. We conduct three …
