Zusammenfassung:The present investigation deals with the validation of the experimentally obtained biaxial true stress-true strain curves of the HCT 780 degree C sheet material from the bulge test with the help of the FEA. Furthermore the investigation handles the consideration of the bending influence via the blank curvature evaluation with an optical measurement system Gom ARAMIS.
