Study on the Differential Thickness Ratio Effect on Formability of TWB Based on Numeric Simulation
The differential thickness ratio of blanks plays an important role on the formability of TWB. The formability of TWB square cup is analyzed by numeric simulation in differential thickness ratio. The laws influencing the formability of TWB square cup are summarized, that the formability of TWB goes worse when the differential thickness ratio increased and it was applied in the production of the center pillar of car door.
