Finite Element Analysis of Influence of Material Anisotropy on the Springback of Advanced High Strength Steel
Abstract
TRIP 870 advanced high strength steel has been chosen for a detailed investigation on the effects of mechanical anisotropy on the springback observed in sheet metal forming. A series of finite element simulations using the Hill'48 anisotropic yield criterion and a standard U-shape forming test based on the NUMISHEET'93 benchmark have been performed. A detailed study of appropriate contact definitions and stress-strain representation has been carried out. Finally, a comparison of springback angles for different orientations of sheet strips relative to the rolling direction is presented.
