The forming limit curve (FLC) is a common method to assess material formability in sheet metal forming processes. It is determined with the Nakajima or Marciniak test according to ISO 12004-2 [1]. The disadvantage of these test procedures is that the

Forming limit strain curves of conventional aluminium alloy AA6014 sheets after loading with non-linear strain paths are presented and compared with D-Bressan macroscopic model of sheet metal rupture by critical shear stress criterion. AA6014 exhibit

For meeting time, cost and quality targets in industrial sheet metal forming processes, correct formability prediction in a very early project stage has become a crucial factor. It is well known that the conventional Forming Limit Curve (FLC), which

Conventional forming limit curves (FLCs) are inappropriate for describing formability for advanced high strength (AHS) steel sheets, since such steel grades experience fracture without localized necking occurrence. The aim of this work was to develop
