TLDR
The statistical breaking position distributions of the nanowires have been investigated to give the effects of strain rate and crystallographic orientation on micro-atomic fluctuation in the symmetric stretching of thenanowires.Abstract:
The failure of the metallic nanowire has raised concerns due to its applied reliability in nanoelectromechanical system. In this article, the breaking failure is studied for the [100], [110], and [111] single-crystal copper nanowires at different strain rates. The statistical breaking position distributions of the nanowires have been investigated to give the effects of strain rate and crystallographic orientation on micro-atomic fluctuation in the symmetric stretching of the nanowires. When the strain rate is less than 0.26% ps-1, macro-breaking position distributions exhibit the anisotropy of micro-atomic fluctuation. However, when the strain rate is larger than 3.54% ps-1, the anisotropy is not obvious because of strong symmetric shocks.read more

Uniaxial tension-induced breaking in the gold nanowire with the influence of defects and temperatures
TL;DR: In this article, the deformation and breaking of the [100] single-crystal gold nanowires containing vacancy defects are studied using molecular dynamics simulations at different temperatures, and the statistical breaking position distributions show the sensitivity of a nanowire to vacancies is based on a competition between constructed vacancies and disordered crystalline structures induced by temperatures.

Canonical dynamics: Equilibrium phase-space distributions
TL;DR: The dynamical steady-state probability density is found in an extended phase space with variables x, p/sub x/, V, epsilon-dot, and zeta, where the x are reduced distances and the two variables epsilus-dot andZeta act as thermodynamic friction coefficients.
