In sheet metal forming operations, formability is usually governed by a great number of parameters such as strain hardening, strain rate sensitivity, and the shape of anisotropic-yield loci. in the present work, the deformation and formability in bore-expanding were examined theoretically and experimentally from aspect of the shape of anisotropic yield loci employing Bassani yield criterion. According to this criterion, a numerical analysis was performed for axi-symmetrical bore-expanding using three investigated materials, AL-Killed steel, EG-LOW carbon steel, and Brass 70/30. The bore-expanding limit was also studied using various necking theories and results were compared with the experimentally determined values. It was concluded that Bassani criterion was useful to predict the deformation and formability in bore-expanding test only at a certain value of r*.
