A common strategy for stabilizing the greenhouse gas concentrations in the atmosphere was the introduction of new emissions limits for cars, and light commercial vehicles. For that reason the automotive industry is facing new challenges in order to fulfill these considerations. One of the strategies attained, is to employ new grades of Advanced High-Strength Steel (AHSS) to replace conventional...

forming limit curve (flc) is an important tool for evaluation of formability of sheet metals subjected to different loading. free bulge of aluminume tubes has been investigated numerically to obtain flc. to verify the numerical results one experimental setup has been manufactured which has the ability of controlling the internal pressure and axial feed. in this study, time and zone of bursting ...

The Form Limit Curve (FLC) is an important and helpful concept for defining sheet metal ductility. ductility of aluminum 6061 alloy was analyzed in this work. current study examined how to enhance the formation curve 6061, which frequently utilized automotive industry. These curves were plotted compared at various temperatures strain levels. Using finite element approach, produced under impact ...
