Springback is an inevitable phenomenon in sheet metal forming, and many researches on its prediction and compensation method have been presented. The use of high-strength steels is now popular; therefore, the demand for effective springback compensation system is increasing. In this study, a novel approach of springback compensation is presented. The proposed framework consists of a springback solver and design system and optimization process. The springback solver is a finite element procedure in which the degenerated shell element is used instead of the typical shell element. This allows the designer to access directly to the resultant stresses such as the bending moment that is a major cause of springback. By our system, mechanically reasonable springback compensation is possible whereas the conventional compensation method only uses geometrical information that may lead to non-realistic solution. The authors have developed a system based on the proposed procedure to demonstrate the effectiveness of the presented strategy and applied it to some forming situations. In this paper, the overview of our approach and the latest progress is reported.
