摘要：By molecular dynamics method, the tensile processes of nano-single crystal copper with the crack front existence hole were simulated, and the effect of different hole position to crack propagation mechanism was analyzed. The results indicate that as the hole position and crack tip came more closer, dislocation glide would be more obvious in the model interior under the load, the crack tip opening increased lead to occur the typical crack tip deactivation. The more obvious crack branch approached to the hole position, the easier to occurred crack expansion. © (2013) Trans Tech Publications, Switzerland.
