Mechanical deformation study of copper nanowire using atomistic simulation

We investigated mechanical deformations of Cu{100} nanowires using the stee pest-descent method. We simulated the cases of elongation, shearing, rotati on and rotated elongation. Before the first yielding nanowires preserve the elastic stage, and after this mechanical deformations proceed in alternati ng quasi-elastic and yielding stages. In the case of rotation deformation, the torque was inversely proportional to the tension force. It was shown th at a nanowire in the case of rotated elongation is deformed more easily tha n one in cases of both elongation and rotation.
