“…Among the material models accounting for these additional effects, that of Teodosiu and Hu [33,34] has been used by a number of authors e.g. [3][4][5]11] to model the induced anisotropic hardening behavior and investigate its effect on forming processes [4,15,36].…”

This work focuses on the modeling of the evolution of anisotropy induced by the development of the dislocation microstructure. A model formulated at the engineering scale in the context of classical metal plasticity and a model formulated in the context of crystal plasticity are presented. Images obtained by transmission-electron microscopy (TEM) show the influence of the strain path on the evolution of anisotropy for the case of two common materials used in sheet metal forming, DC06 and AA6016-T4. Both models are capable of accounting for the transient behavior observed after changes in loading path for fcc and bcc metals. The evolution of the internal variables of the models is correlated with the evolution of the dislocation structure observed by TEM investigations.

“…Variable P is a second order-tensor that depicts the polarity of the persistent dislocation structures (PDSs in [1]) and S is a fourth-order tensor that describes the directional strength of the PDSs. Scalar R represents the isotropic hardening due to randomly distributed dislocations and the second-order tensor X is the back stress.…”

“…Different numerical solutions can be investigated. In this study, the method proposed by Alves [12,13] and Balan using the plastic strain rate direction at the end of the step for the decomposition of S was compared with Hoferlin's method [1,14] using N p e& at the beginning of the step.…”

Abstract. In the present study, deep drawing simulations were investigated using a recently developed mixed type finite element (FE): the BWD3D. The main formulation of the element is described, with particular focus on the shear locking treatment. Two hardening models used in the presented simulations are described: the isotropic Swift's model and the physically based microstructural Teodosiu and Hu model. Finally, deep drawing results, in terms of earing profile, are compared to experiment. Special attention is paid to the effects of texture evolution and hardening models; the method used to implement Teodosiu and Hu hardening model is also discussed.
