Texture-Based Modeling of Sheet Metal Forming and Springback
In this paper the application of a crystal plasticity model for body-centered cubic crystals in the simulation of a sheet metal forming process is discussed. The material model parameters are identiﬁed by a combination of a texture approximation procedure and a conventional parameter identiﬁcation scheme. In the application of a cup drawing process the model shows an improvement of the strain and earing prediction as well as the qualitative springback results in comparison with a conventional phenomenological model.
