Abstract
The purpose of this work is to present results from an ongoing study on how the presence of surfaces influences the buckling properties of nanowires. This study is performed using molecular statics simulations where the interatomic interaction is modelled using an embedded atom potential (EAM) fitted to gold properties. The considered nanowires have rectangular cross sections with cross sectional dimensions spanning from 2-6 nm and aspect ratios between 20-50. Three different crystallographic orientations have been considered; [100]/\{100\}, [100]/\{110\} and [110]/\{110\}\{100\}. The simulations show that depending on how the crystal is oriented the critical load may increase or decrease in comparison with the bulk counterpart. The [100] systems display decreases in the critical forces in comparison with the bulk, whereas for the [110] system the relative critical force increases.
