In this paper, the capability of the four different yield functions to predict forming limit diagrams of continuous cast AA-5754 Aluminum sheet have been compared with focus on the differences in the predicted limit strains based on the method of determining the yield function parameters that do not employ a linear transformation tensor on the stress tensor. The yield functions proposed by Hill (1948, 1990 and 1993) and Barlat (1989), which have been successfully used to predict material anisotropy in aluminum alloys in the literature, have been considered in this study. The forming limit diagrams (FLDs) have been calculated numerically based on these yield functions together with the Marciniak-Kuczynski (M-K) approach.
