Abstract

The use of biaxial data in sheet metal forming simulation of a DP600 steel sheet is investigated. The biaxial strain data is experimentally determined and the stresses are calculated by the inverse finite element method. Then the biaxial flow curve is formed by the Hill 48 material model. The simulation results using tensile and biaxial data are compared with experimental data for an industrial part. Results reveal that the finite element simulations performed by biaxial data display higher accuracy than the tensile data.
