A material strength depends on its microstructure, which in turn, is controlled by an
engineering process. Strengthening mechanisms like work hardening, precipitate, and grain …

Recent experiments on nanostructured materials, such as nanoparticles, nanowires,
nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of “ultra-strength” …

In crystalline materials, plastic deformation occurs by the motion of dislocations, and the
regions between individual crystallites, called grain boundaries, act as obstacles to …

Atomic-level modeling of materials provides fundamental insights into phase stability,
structure and properties of crystalline defects, and to physical mechanisms of many …

This article reviews concepts and techniques for performing instrumented tensile testing of
materials at small dimensions. State-of-the-art methods to probe tensile behavior of micro …

We report the synthesis, mechanical properties, and deformation mechanisms of
polycrystalline, platinum nanocylinders of grain size d= 12 nm. The number of grains across …

Spatial coordinate transformations have helped simplifying mathematical issues and solving
complex boundary-value problems in physics for decades already. More recently, material …

Nanocrystalline Cu–Ta alloys belong to an emerging class of immiscible high-strength
materials with a significant potential for high-temperature applications. Using molecular …

We report on molecular dynamics simulations of an isolated cylindrical grain in copper
shrinking under capillary forces. At low temperatures, the coupling between grain boundary …

Previous simulation and experimental studies have shown that some grain boundaries
(GBs) can couple to applied shear stresses and be moved by them, producing shear …
