Sažetak
In this paper, non-associated plasticity formulation based on an asymmetric yield criterion is developed and investigated in predicting cylindrical cup drawing of the aluminium alloy Al2008-T4. The analyzed asymmetric yield criterion is derived by extending the original orthotropic Karafillis-Boyce equivalent stress term with a linear combination of the normal stress components. The results of cup drawing for Al2008-T4 sheet sample are evaluated by comparison with experimental data and predictions obtained by associated formulation based on orthotropic Barlat(1996) yield function corrected with initial back stress. The simulation results clearly indicate that the cup heights are affected by the yield stress representation.
