The Influence of Texture Development on the Plastic Behaviour of Polycrystals
A usual theory of continuous media is based on the assumption that the material is mainly homogeneous and that isotropy is its natural state. In reality a technical medium is an assembly of grains or crystallites with different orientations of their lattice each of them being highly anisotropic. Isotropy is — if it is observed globally — the result of a random distribution of the different orientations. A very realistic model of these polycrystals has to consider the grains and their orientations.
