Abstract

Formability and its prediction of high-strength steels is an important research subject for forming specialists and researchers in this field. Springback and its accurate prediction of high-strength steels are very common issues in metal forming processes. In this article, the impact of blank holding force and friction on the parts springback made of dual-phase steel was studied. Numerical predictions of the springback effect were conducted using nine combinations of yield criteria and hardening rules. Results from experiments were evaluated and compared with results from numerical simulations. The use of lower blank holding forces and PE foil can reduce springback by a significant amount. Numerical simulations where the Yoshida-Uemori hardening rule was applied produced more accurate springback prediction results compared to simulations that used Krupkowski and Hollomon's isotropic hardening rules in number of cases.

摘要

高强度钢的可成形性及其预测是该领域成型专家和研究人员的重要研究课题。高强度钢的回弹及其精确预测是金属成型过程中非常常见的问题。本文研究了压边力和摩擦对双相钢制成零件回弹的影响。使用九种屈服准则和硬化规则的组合对回弹效应进行了数值预测。对实验结果进行了评估，并与数值模拟结果进行了比较。使用较低的压边力和PE箔可以显著减少回弹。在许多情况下，与使用Krupkowski和Hollomon各向同性硬化规则的模拟相比，应用吉田-上森硬化规则的数值模拟产生了更准确的回弹预测结果。
