Abstract
With the increasing application of hot-stamped parts to automobile bodies and warm-drawn parts of magnesium alloys to electrical devices, simulation has become a basic approach to formability evaluation when designing parts and tools. However, the thermal-mechanical coupling phenomena induced in the hot-stamping process and warm-drawing process are complicated. To accurately simulate these complicated phenomena, a finite-element model for B-pillar hot stamping was created and transient temperature distribution was simulated. The thickness distribution and hardness distribution in a hot stamped B-pillar were predicted. Furthermore, a temperature-dependent anisotropic material model combined with the Hill48 yield function was developed for the simulation of the warm-drawing of magnesium alloys. The predicted results agreed well with experimental ones and simulation accuracy was demonstrated using the newly developed models.
