Notes:
In order to solve the problem existed in the numerical simulation of sheet metal forming forits use the strain-based forming limit diagram as criterion, which has the flaw of dependence on thestrain paths, this paper develops the finite element analysis program based on the stress forming limitcriterion applicable to the blank plastic forming technique, which follows the stress-straintransformation relationship when the sheet metal is undergoing plastic deformation, chooses Hill’squadratic normal anisotropic criterion as computational model and selects the commercial finiteelement code Dynaform as its development environment. Also it be analyzed the finite elementnumerical simulation results of two deep drawing parts by the developed program module andrealizes the prediction of sheet metal forming limit adopting the FLSD as criterion. The stress-basedforming limit criterion for the developed program provides a new means to analyze the forming limitfor the multistage sheet metal forming
