Abstract
In metal forming processes, the accuracy of their simulations depends on the ability of the constitutive model to describe the relevant features of the material. For the inclusion of the texture-induced anisotropy, micro-macro models are favourable. However, the numerical effort must be drastically reduced for practical applications. A reduction of the number of crystallites on the macroscale will, unfortunately, result in an overestimation of the anisotropy. In this paper, three different methods are suggested which lead to a reduction of the numerical effort, for each of which this overestimation has been avoided by different means.
