| Abstract: Molecular dynamics simulations were used to study the deformation behaviors of the [100] single-crystal copper nanowire subjected to uniaxial tension. The tensile strain rates are 0.02%·ps-1, 0.2%·ps-1 and 2.0%·ps-1, and the simulated temperatures are 100, 300 and 600 K, respectively. The deformation behaviors, mechanical property, radial distribution function and the energy curve were studied in detail. The results show that the deformation of the nanowire at low, middle and high strain rates correspond to the equilibrium, quasi-equilibrium and non-equilibrium states, respectively. The structure reveals crystalline, local disorder and amorphous forms at low, middle and high temperature, respectively. |
