A computer program was developed for simulating the dynamics of an arbitrary 2-dimensional dislocation–disclination ensemble. It was based upon molecular dynamics principles: individual interacting particles were taken to be edge dislocations and dipoles of partial wedge disclinations. Pure Cu was considered as an example for simulating the glide of one dislocation near to an immobile dipole, for various orientations of the dipole and under various initial conditions. The dislocation dynamics were shown to be determined mainly by the distribution of the elastic field of the disclination dipole rather than by the initial velocity of the dislocation.
