The texture evolution of a planar polycrystal

In this paper, the texture evolution for a two-dimensional polycrystal is i nvestigated in the cases of biaxial stretching and simple shear. The descri ption of this texture is analyzed, using Taylor's assumption, for an aggreg ate consisting of rigid plastic single crystals with plane symmetry. An ana lytical solution is obtained for the orientation distribution function desc ribing the aggregate textures. The evolution of this texture, for large str ain, induces preferential orientations which are discussed. (C) 2000 Elsevi er Science Ltd. All rights reserved.
