Forming–Structural-Coupled Analysis: The Method to Predict Die Deformation Using Quick Simulations

This research analyzed die deformationDie 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 deformationDie deformation, forming–structural-coupled analysisCoupled analysis was implemented. In the analysis, two simulations were used: AutoFormAutoForm and midas MeshFreeMidas MeshFree which are known as advantageous software for reliable results and quick-solving. As a sequel to the coupled analysisCoupled 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 to 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 deformationDie deformation without spending much time.
