Abstract

The springback phenomenon in sheet metal stamping will lead to problems in subsequent assembling, and cannot guarantee parts dimensional accuracy, it is necessary to research spring-back parts effect in part stamping molding. Due to the high strength steel has a high yield strength, the springback after unloading increases, advanced high strength steel plates show unique material properties in reverse loading, the Bauschinger effect, which makes it more difficult to predict springback accurately. In this paper, by finite element simulation of stamping process of DP steel s shape beam in Autoform, the Bauschinger effect was taken into account. The effect of parameters of kinematic hardening model in Bauschinger effect on the springback after stamping molding was mainly discussed. The result shows that, with the increasing of transient softening rate κ, the maximum springback increases. The increasing of Stagnation Ratio ζ reduces the springback.
