Improvement on CAE Model for Accurate Torsional Springback Prediction in High Strength Steel Part Forming

Abstract:

It is difficult to predict springback, torsion in particular, with great accuracy by FE simulation. In this study, the effects of anisotropic yield functions of the blank and elastic deformation of the tools on springback are investigated in order to improve the accuracy of torsional springback prediction in high strength steel part forming. The effects of anisotropic yield functions on the torsional springback in curved hat forming were compared, using parameter sets derived from various experimental methods: uniaxial tensile tests only; hydrostatic bulge tests and uniaxial tension tests; uniaxial and biaxial tensile tests. FE analysis of press forming taking account of tool deformations was carried out and the results were compared with the ones of FE simulation with rigid tools and experimental results. It is demonstrated that FE simulated torsional springback with deformable tool model has better correlation with experimental one than with rigid tool model.
