Abstract: A method for compensating springback of a part includes running a finite element analysis (FEA) simulation of forming a panel using a model of forming die such that a panel with springback is simulated, determining at least two zero springback locations on the panel where hanging apertures are simulated, running an FEA simulation of the panel hanging from the hanging apertures, and comparing a geometry of the hanging panel to a geometry of a reference panel such that a difference between the geometry of the hanging panel and the geometry of the reference panel due to the springback is determined and compensated.
