Mechanical deformation study of copper nanowire using atomistic simulation

Abstract

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