Tensile testing of cylindrical multi-shell Cu nanowire
  We have simulated the tensile testing of cylindrical multi-shell Cu nanowire. Elongated cylindrical multi-shell Cu nanowire was transformed into a pentagonal structure. Pentagonal nanowires are composed of a central atomic strand and pentagonal tubes made of five-times-folded <110>{100} sheets.
