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.

Defects in ultrathin copper nanowires: Atomistic simulations
TL;DR: Oshima et al. as mentioned in this paper performed atomistic simulations for cylindrical multishell (CMS)-type Cu nanowires containing defects and found that vacancies formed in the outer shell of a CMS-type nanowire naturally migrated toward the core.
