Theoretical study on asymmetric fatigue cycling (ratcheting) for copper nano-wire has been performed using molecular dynamic simulation with Embedded Atom Method Finnis-Sinclair potential. The fatigue behavior has been investigated under varying stress rations as well as at different temperatures. The results include that the accumulation of ratcheting strain increases with both increasing stress ratio and temperature. The simulation results of ratcheting strain are in good agreement with some reported experimental results.
