Screw dislocation cross-slip

FCC Cu, Mishin EAM potential, 1331 atoms per element in the coarse-grained domain. Results using larger models are published in Xu et al., 2017.

In the figure below, the atoms that fill in the jagged interstices are not shown for a better visualization of the elements. In the Langevin dynamic simulation, a screw dislocation on the (1¯11¯)(\bar{1}1\bar{1}) plane is first created; then subject to a γzy\gamma_{zy} simple shear strain, it crosses slip onto the (11¯1¯)(1\bar{1}\bar{1}).
