| Abstract: | The self organised dislocation structures during the cyclic deformation of a copper single crystal were simulated by using three thousands positive negative parallel straight edge dislocations randomly distributing on the primary slip planes as the initial conditions and by using the method of discrete dislocation dynamics. A big dipole dislocation structure was found. The vein and wall structures of dynamic equilibrium were obtained. Computer simulation results agree with the experimental results. |
