Study on the relationship between surface and dislocation of nanoporous copper under cyclic shear loading

Abstract: In this paper, molecular dynamics simulation is conducted to study the relationship between the surface and dislocation of nanoporous copper under cyclic shear loading. The results show that the dislocation and the surface have both mutual promotion and competition relationship. On one hand, the surface becomes rough owing to reconstruction caused by cyclic shear, which promotes the dislocation activities, while the dislocation activities also accelerate the process of surface reconstruction. On the other hand… Show more
