N2 - In order to investigate the mechanical properties of single crystal Cu nanorod with preset defects, the multiscale unixial tension simulation models of nanorods with two different crystallographic orientations are established. In two orientations, the dislocations are emitted firstly from the notch tip. The results show that the defect evolution, stress-strain curves and train energy vary with different crystallographic orientations. In x[111],y[110],z[112] setup, the deformation is ductile mode and it is fracture fashion in the x[112],y[111],z[110] setup.
