FE simulation study of deep drawing process of SUS304 cups having no delayed cracks under enhanced blank holding force
In the experiment, delayed cracks in deep drawing processes of metastable stainless steel SUS304 cylindrical cups were prevented using elevated blank holding force aided by nanolubrication. Besides tensile residual hoop stresses, the elimination of the cracks was also attributed to the change in wal...
