%X The plastic deformation behavior and stretch flangeability of a high Mn TWIP steel sheet sample were investigated. Uniaxial tension, disk,compression and hydraulic bulge tests were conducted to characterize the flow behavior and plastic anisotropy of the material. Experimental,investigations and finite element simulations of the hole expansion test were also performed. The finite element simulations were carried,out using the finite element code ABAQUS with three yield criteria: von Mises, Hill 1948 and Yld2000-2d.
