Abstract
Initially aimed at low carbon steels, the proposed method is shown to be applicable to stainless steel and aluminium alloys as well. The accuracy of the predicted stress factors has been verified by comparing simulation results with measurements of strain distribution, punch force, displacement and temperature. The comparisons of three strain paths on Nakazima specimens taken from a forming steel and a dual phase steel show a very good agreement between the measured and simulation results. Additionally, cross die tests on eleven materials, ranging from forming steels to Advanced High Strength Steels, have been used to assess the model. The results demonstrate that the proposed method of generating parameters for advanced yield criteria from tensile mechanical properties is highly accurate and very easy to use.
