Using a rate-sensitive crystal plasticity model together with the full constraint Taylor theory, the formation of textures during biaxial stretching of FCC sheet metals is investigated in detail. Three-dimensional lattice rotation fields, orientation evolution and polycrystalline texture development are simulated for the entire range of biaxial strain ratio. The investigation discloses the paths of orientation development and respective stable end orientations, as well as the relation between the evolution paths and the biaxial strain ratio. Our results show that the formation of textures depends mainly on the behaviour of the α- and βρ fibres in biaxial stretching. The strain ratio affects the composition of the βρ-fibre, as well as the flow direction and velocity of orientations towards and along α and βρ, and thus results in different biaxial-stretching textures. The predictions of FCC biaxial-stretching textures are compared with experimental observations reported in literature. Finally, we discuss the influence of complex strain paths on texture formation.
