Sažetak
The increasing exploitation conditions on the engi-neering components promote equally fast and adap-tive manufacturing processes. This is apparent espe-cially in the industry where metal forming is applied. The optimization and modelling of the forming pro-cess depends on Finite Element (FE) simulations where the defined material mechanical properties play a key role. For that purpose, mechanical tests need to be conducted to quantify the material behav-ior. However, the conventional uniaxial tensile tests do not provide comprehensive material information to predict the material response under complex workloads. Arcan fixture stands out as one of the most versatile fixture in terms of available loading possibilities, namely tensile, simple shear and the mixed-mode loading. The proposed rig employs but-terfly samples with symmetric V notches in the gauge area to ensure uniform stress state between the notches. However, mechanical tests involving thin sheets subjected to simple shear often experience buckling which consequently prevents accurate char-acterization of the investigated material. The com-plex geometry of the butterfly samples demands the use of full-field measurement methods, from which Digital Image Correlation (DIC) stands out as the most widely used method. Such approach provides more detailed insight into the material behavior and localization phenomena.
