FEM simulations are nowadays an integral part of nearly every forming tool development process, especially for the prediction of the overall process feasibility. The traditional forming limit curve (FLC), often fails in delivering a good prediction as many parts fail under non-proportional loading. The Generalized Forming Limit Concept (GLFC), extends the traditional FLC to account for this effect. However, the original GFLC is an isotropic approach and it thus does not account for changes in the loading direction with respect to the rolling direction. In this paper, the functionality of the new 3D-GFLC, which accounts for the mentioned parameter, is demonstrated using a real industrial component. For this purpose, the 3D-GFLC was implemented into the FEM software and validated based on experimental investigations.
