【 摘 要 】

Car manufacturing has been significantly influenced by sheet metal forming developments, thus the requirements and developments in car manufacturing have decisive role in the development of sheet metal forming, too. The automotive industry is facing challenges of reducing body weight in consideration of environmental problems and higher collision safety. These requirements are being addressed by the application of various dual-phase steels, ultra and extra advanced high strength steels (UHSS, XAHSS). Forming Limit Diagrams (FLD) are the most appropriate tools to characterize the formability of sheet metals. Theoretical and experimental investigations of forming limit diagrams are in the forefront of todays' research activities. In this paper, an up-to-date research methodology elaborated and applied at the Department of Mechanical Technology at the University of Miskolc will be shown.
