 Abstract
In metalforming, ductile fracture criteria have been used for the purpose of predicting fracture occurrence in the stage of process design prior to manufacturing. In the present investigation, some of popular criteria are reviewed to find the most suitable one among them. As a result, it is found that the modified Cockroft and Latham criterion is better than others. The reasons are: it agrees with Roy's and McClintock's void growth models, it is more general than Oyane's and Kuhn's criteria, and it predicts fractures in compression as well as in tension well. However, it is also found that the criterion is incapable of predicting fractures in torsion.
