A simulation which was designed for the investigation of the transition of a uniformly strained crystal, from a defect-free state to a defective state, was applied to a quasi 3-dimensional quasi-static system with periodic boundary conditions. It was found that structural changes occurred in several stages as the strain was increased. In the first stage, the positions of the atoms at the sites of the uniformly strained lattice were stable. The second stage was characterized by the generation of small-amplitude sinusoidal displacement waves of the atoms. Dislocations of the primary slip system formed in the third stage, and dislocations of the secondary slip system formed in the fourth stage.
