Simulation of Setup (IMAGE) Moscow Institute of Physics and Technology Caption This image shows: (a) Simulation setup for studying dislocation dynamics in a uranium dioxide crystal under applied shear stress σxz. Uranium atoms on lattice points of the perfect uranium sublattice within the uranium oxide crystal are shown in green. The line defect that corresponds to a distortion of the perfect crystal lattice is shown in blue. (b) The perfect uranium dioxide crystal structure with the green and red spheres representing uranium and oxygen atoms respectively.
