It was noted that, when a face-centered-cubic single crystal was elongated uniaxially, the characteristics of the deformation behavior could be theoretically predicted. Such characteristics included the amount of glide strain, the operating slip system and the moving path of the tensile axis. The Bowen-Christian equations were modified in order to explain differences in glide strains. It was found that the difference in glide strains could depend not only upon the activation of secondary slip systems but also upon the accumulation of dislocations.
