Numerical Simulation and Analysis of High-Strength Steel Autobody Panel Stamping
The high-strength steel blanks with higher yield strength had introduced many challenging formability problems for the stamping process. However, in some situations the multi-stage process is a very effective solution for the stamping of high-strength blanks with a relatively lower formability than that of commonly steel blanks. In the multi-stage process, the change of strain path will be beneficial to the reduction of strain peaks and the utilization of the potential plasticity.
