Study on the Influence of the Springback on the Hole Expansion Ratio Characterization

Materials Science: Materials Review, 2018
Material formability has become one of the main problems, together with the springback, when stamping high added-value components for the automotive industry. The pursuit of weight reduction has led to higher strength alloys which show a lower formability. Among the different formability criteria (e.g.
