Two-level (macro- and microlevels) model for polycrystalline materials large plastic deformation describing with texturing and forming elastic and plastic properties anisotropy is introducing. The deformation processes modeling was realize by constitutive equations including internal variables which are mesolevel- defined. For internal variables evolution analysis transgranular and intergranular sliping, also rotational modes were discount. Parallelizable capabilities for effective realization are discussed.
