Abstract

The paper presents a quantitative analysis referring to the variability of the uniaxial and biaxial parameters describing the plastic anisotropy and hardening of the DC01 steel sheets and the influence of this variability on the results of the simulation of the sheet metal processes and on the prediction of the forming limit curves. The experimental data is acquired by means of tensile tests performed along three directions in the plane of the sheet metals, using flat specimens cut from two batches. The Nakazima test has been used to determine the forming limit curves. The predicted forming limit curves are in good agreement with the experimental ones.
