The formulation of constitutive models at finite strain using local objective frames is applied to solids with microstructure. Priviledged space frames are introduced at both the material level and the micro structure level. For single crystals, the method leads to a model almost equivalent to Mandel's theory. For polycrystals, an explicit concentration rule written in the corotational frame is proposed. Simulations of texture evolutions are then presented.
