Objectives: To study the yield behavior and plastic flow of an anisotropic sheet metal during forming operations, various mathematical formulations of the plastic state of the sheet metals have been proposed, known as yield functions. Different yield functions pertain to different criteria and have different characteristics. Methods/Statistical Analysis: There are several yield criteria proposed for the study of yield behaviors of sheet metals. This paper aims at reviewing the most frequently and commonly employed for the purpose yield criteria i.e. Hill 1948, Barlat 1989, Hill 1990 and BBC 2000. The study is focused on discussing the form of each criterion, their implementation details and comparing their predictive accuracies. Findings: The methods followed to obtain the yield surface diagram have been reviewed and discussed. Application/Improvement: Inference has been drawn based upon the agreement between theoretical and experimental value for a particular case.
Keywords: Accuracy Index, Anisotropic Coefficients, Yield Criteria
