Automotive structural parts made out of Advanced High Strength Steel (AHSS) are often produced in a multistage forming process using progressive dies or transfer dies. During each forming stage the steel is subjected to work hardening, which affects the formability of the steel in the subsequent forming operation. Edge flanging and in-plane edge stretching operations are forming modes that are typically employed in the last stage of the multistage forming processes. In this study, the multistage forming process was simulated by pre-straining a DP980 steel in a biaxial strain path with various strain levels followed by edge flanging and in-plane edge stretching. The biaxial prestrains were obtained using the Marciniak stretch test and edge flanging and in-plane edge stretching were accomplished by the hole expansion test using a flat punch and a conical punch, respectively. The measurement of the edge strain limits at fracture for each tooling set up was performed using the Digital Image Correlation (DIC) technique. The results show that biaxial prestraining has no significant effect on edge flanging, however biaxial prestrain reduces formability in the in-plane edge stretching mode. This behavior is related to the relative uniformity of the strain distribution around the expanding hole.
