Abstract:
1. A computer readable storage medium storing one or more computer programs comprising a method for designing a die used in stamping a part having final dimensions, the method comprising: creating a finite element mesh of the part; simulating a stamping of the part in the die with the finite element mesh; predicting a springback of the part based on the simulated stamping of the part; automatically compensating the shape of the die of the finite element simulation based on the springback such that after the springback the part will have the final dimensions desired, wherein automatically compensating the shape of the die comprises projecting a location on the finite element mesh of the part to an adjacent location on a finite element mesh of the die before springback; and receiving a scale factor and refining the compensated die by applying the scale factor to the compensated die or a further iteration of the compensated die.
