Abstract

The ductile fracture criterion (DFC) is widely used to predict the forming limit of sheet metal, and the material constants in the criterion need to be determined by the destructive tests. In order to increase the DFC predication accuracy, the key factor is improving the quality of material constants in the DFC. The smoothing finite-element method is developed to obtain the real fracture strain and the accurate material constants. Calculations are carried out for various strain paths of elliptical hydro-bulging process. The result demonstrates SFER method improved the accuracy of the DFC’s prediction.
