Prediction of forming limit diagram using the Marciniak-Kuczynski method for Ti-6Al-4V using different material models
Abstract
The forming limit diagram (FLD) is a widely used tool to assess the formability of a metalsheet [1]. The current study aims to investigate the influence of strain rate, material anisotropy andhardening on the FLD of Ti-6Al-4V predicted by the well-known Marciniak-Kuczynski (M-K)method. The tensile data of quasi-static (8∙10-5 s-1), intermediate (0.5 s-1) and dynamic experiments(approximately 1000 s-1) on Ti-6Al-4V sheet are available at three different orientations, with respectto the rolling direction: 0°, 45° and 90°. Different hardening models are taken into account. Also, vonMises and Hill yield criterion are considered. The results show that the influence of the hardeninglaw on FLD is significant. In particular, the most conservative limit strains are predicted by the Vocelaw because of its saturation characteristic. The yield criterion is found to only affect the right part ofthe FLD. Regarding the strain rate influence, the left part of the FLD is mainly dominated by theamount of uniform elongation, while the right part is strongly dependent on the yield function used.Therefore, for this region the effects of strain rate and yield function are difficult to distinguish.Finally, the effect of material anisotropy on the FLD is significant. Under quasi-static conditions, theLankford coefficient seems to be the driving factor in uniaxial and equibiaxial deformation. However,in plane strain conditions the effect of the strain hardening exponent is dominant.
