A zero temperature simulation of tension properties of nano crystal copper wire has been studied by embedded atom method (EAM) and molecular dynamics. The surface effects on the distribution of atom energy and stress on cross section were investigated. It is found that the initial elastic modulus is decreased by surface relaxation, and the surface effect plays an important role in the evolution and distribution of stress.
