Comparisons in mechanical properties of various copper nanowires under torsion: molecular dynamics simulation
Source abstract
Abstract
The torsion of classical single crystal copper, hollow single crystal copper, and single crystal copper with single crystal silver shell nanowires is simulated by molecular dynamics method. It is found that the torsion process of copper nanowires can be divided into three phases: elastic phase, plastic phase, and deforming destroying phase, in which there is a “twinning-detwinning-twinning” periodic deformation mechanism. Axial through holes will increase the instability of nanowires and weaken their ability to endure elastic deformation. Furthermore, the effect of silver shell thickness on the mechanical properties of copper silver core–shell nanowires is discussed. The results show that the increase of the shell region will lead to the expansion of the lattice imbalance region, which has a great impact on the torsional deformation of copper alloy nanowires.
