abstract = {In this work, the stretch flangeability of a TWIP steel sheet sample was investigated both experimentally and numerically through the hole expansion test. Uniaxial tension and disk compression tests were performed to characterize the flow behavior and plastic anisotropy for the TWIP steel sheet sample. The punch load-stroke curve, hole diameter and specimen surface strain distribution near the hole was measured. Then finite element simulations of the hole expansion test were carried out using the finite element code ABAQUS with three yield criteria: von Mises, Hill 1948 and Yld2000-2d. The predicted and experimental results were compared in terms of the final hole radii and the strain distribution.},
