Does thinner material has more springback than thick?
5 answers
Thinner materials generally exhibit more springback compared to thicker materials. The thickness reduction in thin packaging sheets has led to higher strength properties but lower plastic properties, resulting in increased springback tendencies. Studies have shown that as the material thickness decreases, the springback angle tends to increase, especially in the thin zones. Additionally, the stress concentration in thinner zones contributes to more noticeable thickness thinning and higher springback angles. Research on high-strength steels and aluminum after forming processes has demonstrated that the stress gap between thin and thick sides increases with material strength, affecting the springback behavior. Therefore, thinner materials are prone to experiencing more significant springback effects compared to thicker materials due to their inherent characteristics and stress distribution.
