The deformation and breaking behaviors of metallic nanowires have raised concerns owing to their applied reliability in a nanoelectromechanical system. In this paper, molecular dynamics simulations are used to study the deformation and breaking properties of the [1 0 0] oriented single-crystal copper nanowires subjected to uniaxial tension at different temperatures. With a dependence of temperature, statistical samples identify a most probable breaking position of the nanowire, and the “most probable” feature reveals that the breaking behavior is correlated with nanoscale compression wave propagation at different temperatures. Macro-breaking position distributions confirm the influence of temperature on micro-atomic fluctuation during the symmetric stretching of the nanowires.
► The breaking behavior of metallic nanowires are various among the samples. ► Statistical feature identifies a most probable breaking position (MPBP). ► MPBP is correlated with the compression wave propagation. ► Breaking position distribution reveals the influence atomic fluctuation during the nanostretching.
