Molecular dynamics simulation of gold nanowires under tensile loading

This paper presents numerical simulations of gold nanowires under tensile loading at various section cross sizes with molecular dynamics simulation.The simulation results from our work show that for the same length,the elastic modulus decreases with decreasing sizes of cross-sections,while yielding stress increases with decreasing sizes of cross-sections of gold nanowires and the yielding delays.The deformation of gold nanowire is consistent with the stress strain curve.The deformation of gold nanowire is not notable in the elastic part of the stress-strain curve and stacking faults substantially emerge in the gold nanowire with increasing strain rate.
