This research analyzed die deformation caused by sheet metal forming stress. The stress results in elastic deformation on the die as well as plastic deformation on the panels. To predict the exact amount of the die deformation, forming-structural coupled analysis was implemented. In the analysis, two simulations were used, AutoForm and midas MeshFree which are known as advantageous software for reliable results and quick-solving. As a sequel to the coupled analysis, we could figure out the exact deformation more precisely and quickly, compared to the previous methods that had consumed much time. The numerical results were significantly analogous with the measured results. Ultimately, this research proposes a widely applicable, accessible and time-effective process to assess die deformability. Through this practical methodology, it is expected that die design departments would be able to predict die deformation without spending much time.
