Molecular dynamics (MD) simulations are performed to study crystalline plasticity during
nanoindentation by comparing the elastic-plastic response of three copper substrates with …

A model of micro-pillar plasticity controlled by the nucleation of dislocations at free surfaces
was developed using methods of dislocation dynamics innovated by Johnston and Gilman …

We evaluate the extent to which two mechanisms contribute to the observed size effect of the
ultimate yield strength of micropillars of diameters in the range of 1–30μm: dislocation pile …

The results of both experimental studies and molecular dynamics simulations indicate that
crystals exhibit strong size effects at the sub-micron scale: smaller is stronger. Until recently …

The results are presented of uniaxial tensile testing of single crystalline electroplated copper
nanopillars with diameters between 75 nm and 165 nm fabricated without the use of a …

The mechanical behaviour of very small volumes differs from what is typically observed on
the macrolevel. In particular, thin metal films with nanometer-sized coatings possess …

Molecular dynamics simulations performed on< 110> Cu nanopillars revealed significant
difference in the deformation behavior of nanopillars with and without twin boundary. The …

Micropillar compression testing with repeated jumps in strain rate is used to circumvent
inherent difficulties associated with nanoindentation and tensile testing of free-standing …

Nanocrystalline metals generally exhibit high strengths and good fatigue resistance. Their
