Abstract

In recent years, the high strength steel has been used widely to prove the advantage of lightweight used in automotive industry. The drawbacks occurred in the stamping procedure are thinning, springback and so on. And many process parameters affect the forming quality significantly, such as friction coefficient and blank holder force (BHF). In this paper, the effect of process parameters on the forming defects is investigated. The design of test was utilized and the finite element model was established and applied. The aim of this study is to get a further understanding on the stamping of high strength steel.
