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 …

We demonstrate, through three-dimensional discrete dislocation dynamics simulations, that
the complex dynamical response of nano-and microcrystals to external constraints can be …

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 …

We present differences in the mechanical behavior of nanoscale gold and molybdenum
single crystals. A significant strength increase is observed as the size is reduced to 100 nm …

Slowly compressed microcrystals deform via intermittent slip events, observed as
displacement jumps or stress drops. Experiments often use one of two loading modes: an …

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 …

We consider strain hardening of nanostructured materials and propose a physically based
interpretation of their low strain hardening capability in terms of a reduced storage rate of …

We give a bird's-eye view of the plastic deformation of crystals aimed at the statistical
physics community, as well as a broad introduction to the statistical theories of forced rigid …

Mechanical deformation of nanopillars displays features that are distinctly different from the
bulk behavior of single crystals: Yield strength increases with decreasing size and plastic …

Under stress, many crystalline materials exhibit irreversible plastic deformation caused by
the motion of lattice dislocations. In plastically deformed microcrystals, internal dislocation …
