Abstract: Industrial forming processes usually involve complex strain paths, which are typically associated with softening/hardening effects. These can mainly be ascribed to the development of an 'intragranular microstructure' consisting of dislocation cells and cell blocks. This paper addresses a method to incorporate these microstructural details at the grain-scale in a full-constraints Taylor model. The dislocation cells and cell blocks have a significant influence on the anisotropic properties of the material, particularly the r-values. The trends arising from the simulations correspond well with experimental observations. (C) 2001 Elsevier Science B.V. All rights reserved.
