The aim of this study is to explore the effects of stress triaxiality and Lode angle parameter as a function of the cup height in the deep drawing process. For this purpose, deep drawing of square cups made of AISI304 steel are analyzed numerically by using von Mises and Hill’48 yield criteria with isotropic hardening. The fracture of the sheet is predicted by applying the Johnson-Cook and the Hosford-Coulomb ductile criteria. The results obtained by using the finite element method are presented in terms of effective plastic strain, triaxiality and Lode angle parameter distributions for the deformed blank. The tensile, compressive and shear nature of the deformation is evaluated by referring the corresponding triaxiality and Lode angle parameter values.
