Summary:

The design of pockets on automotive sheet metal parts can significantly affect part formability. We have developed regression formulas for predicting the failure depth of a symmetric rectangular pocket as a function of the geometric parameters that define the pocket. The formulas were developed by statistically selecting combinations of geometric pocket parameters for formability analysis and using formability simulations to determine the pocket failure depth for each selected parameter combination. The regression formulas were tested by comparing their predictions with simulations for combinations of part parameters not used to develop the formulas
