Purpose: This paper presents the results of experimental, analytical and numerical studies of draw-bend springback on the response of steel blank strips. Design/methodology/approach: Springback, the elastically-driven change of shape of a part after forming, has been simulated with 2-D plane strain finite elements model (ABAQUS). Springback simulations compared with experimental test results under some test conditions and also sidewall curls were further discussed in this paper. Findings: The results validate the finite element approach as a trustworthy tool for predicting the springback parameters for a given set of stamping conditions and material properties. Research limitations/implications: This model is a simple and an efficient way to take apart the responsibilities of the steel maker for the selection of steel to be used and sheet stamping designer for the selection of the forming conditions to work in a safety zone in order to increase the reliability of the stamped structures. Originality/value: Experimental and finite element analyses have been conducted on blank strips of Hadfield steel (high strength steel) and Mild steel with similar operational conditions.
