We study a polycrystalline material that undergoes a rigid‐plastic rate‐independent evolution. Of our particular interest is the creation of texture and the resulting qualitative change in the macroscopic material response: from isotropic to anisotropic. Texture is represented by a crystal orientation distribution function, which associates every spatial point with a probability measure on the set of rotations. We discuss an energetic formulation for the texture evolution in the context of generalized standard materials. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
