摘要：
The mechanical properties and behaviors of < 100 >, < 110 > and < 111 > orientation copper nanowires under torsional loading are investigated using molecular dynamics. The relations of the normalized strain energy and virial torque with twist angle are computed. The orientation dependent plasticity in the single crystal copper nanowires is analyzed by the different modes of nucleation and propagation of dislocation from nanowires surface.
