    A crystal plasticity approach with a phenomenological shear banding mechanism incorporated in a conventional dislocation crystal plasticity model is presented. In the developed framework, the hardening and softening relations are considered both within and between the deformation mechanisms. The study aims to increase the understanding of the importance of hot rolling texture to the shear banding propensity in martensitic steels. In the single crystal simulations performed for selected common rolling textures, it was found that shear band activation and the magnitude of softening are dependent on the initial orientation of the crystal. In general, softening-related shear banding in single crystals was shown to be well reproduced by the model at high plastic strains and high strain rates.
