Sheet Metal Testing and Flow Curve Determination under Multiaxial Conditions

This study comprises the testing of three auto body steels with regard to formability, tensile strength and forming limits under various stress states. Two multiphase steels (DP600, TRIP700) and one ferritic interstitial free (DX54, 1.0306) were characterised. A further main focus of this study is the comparison of experimentally determined flow curves in the bulge test with extrapolated tensile test flow curves. This comparison gives an insight into the predictability and accuracy of extrapolated curve progressions to higher strain ranges.
