The applicability of the phenomenological anisotropic yield functions, i. e., Bassani, Hill's new and conventional, and biquadratic ones, is examined using commercially pure aluminum (A 1100) and killed steel sheets. A method for determining the material constants related to each function with the uniaxial tension test and two compression tests (through-thickness and plane-strain) is presented. It is concluded that though Bassani's function has a few intrinsic problems, it is the most available to predict the yield loci under biaxial tension and the strain distribution in the bore-expanding test.
