(Color online) Evolution of the tensile-induced twinning in a long nanobox with a and , where potential energy is in units of eV. (a) and (b) show the evolution of the twins for an individual surface, while (c) shows the effect of twinning on the entire nanobox.
(Color online) Deformation of long, wide copper nanowires at a strain of , with varying thickness of (a) , (b) , and (c) . Potential energy is in units of eV. Note twinning-dominated deformation for nonsquare cross sectional wires seen in (b) and (c).
(Color online) Deformation of a long copper nanowire by partial dislocation nucleation and propagation at a strain of with cross sectional dimensions of . Potential energy is in units of eV.
Dimensions of simulated copper nanoboxes, given as outer cross sectional edge length by the inner cross sectional edge length ; all numbers represent cubic lattice units (CLU), where for copper. All nanoboxes have a length of .
