Abstract—The effect of material property on the springback of part in stamping process is significant. And it is necessary to study the influence. Traditionally, the material property indices concerned are tensile strain hardening exponent (r), Plastic strain ratio (n), and yield stress. In this study, the effect of tensile strain hardening exponent (r), plastic strain ratio (n) and yield stress on the springback was studied with the help of the design of test, FE analysis, Response surface analysis. The springback increases with the increase of n value and yield stress. And r value shows a slight effect.
Index Terms—Springback, material property, high strength steel.
