Abstract: The plastic anisotropy of a developed 'intragranular microstructure' in the material, consisting of dislocation cells and cell blocks, is often neglected in crystal plasticity deformation models. However, the softening/hardening effects observed in the stress-strain response during complex strain paths, do show the importance of such microstructural features. This paper addresses a method to incorporate cells and cell blocks at the grain-scale in a full-constraints Taylor model. It is shown that latent hardening and polarity of the CBBs are the major characteristics needed to obtain the subtle features of the measured stress-strain responses in "cross tests" and in "Bauschinger tests" in BCC metals.
