Abstract

Abstract Part I of the present work dealt with the initial stage of plastic deformation with grain subdivision into two band families. It covered the situation with different average strains in the individual grains (the non-Taylor case) and the situation with identical average strains in the individual grains (the Taylor case). For the latter situation part I included solutions with 5 plus 3 and with 4 plus 4 active slip systems in the two band families, respectively. In part II we deal with the subsequent stage of plastic deformation (finite strains) for the Taylor case with four active slip systems in each band family. In the subsequent stage the cooperation between the two band families leads to an energetic advantage for grain subdivision, and it leads to a simulated texture with decreased sharpness in accordance with experimental observations. Finally, the physics behind grain subdivision are discussed on the basis of the results in Parts I and II and various general considerations.
