The selection of active slip systems in a crystal subjected to a given strain has been solved by use of an analytical algebraic method based upon the interdependence of the slip systems. In the case of glide on the {110} 〈111〉 or the {111} 〈110〉 slip systems, the application of the maximum‐work principle is reduced to a comparison between only four of the twenty‐eight processes connected with the corresponding stress states found by Bishop & Hill [ Philos. Mag. (1951). 42 , 414–427, 1298–1307]. The proposed method can easily be applied to the case of glide on several sets of slip systems and finally to the case of pencil glide.
