摘要

In this paper, the springack of DP600 steel was characterized under various experimental warm stamping conditions based on Numisheet 1993 benchmark problem. Simulations using the Hensel-Spittelequation for FE modelling at ABAQUS software were performed in order to compare the springback prediction to experimental results. It was found that springback effect decreases as the temperature rises. The FE modelling based on Hensel-Spittel equation was in good agreement to the experimental results with no more than 6% error for θ1 and θ2 springback parameters. Although DP600 steel was originally designed for cold work, the study of this material at different temperatures should improve control of springback of AHSS in deep drawing operations. The springback analysis can lead to a further understanding about the influence of temperature and strain rate over springback effects, avoiding extra costs of tool reworking and enhancing the process control.
