Experimental Investigation on Forming Limit of Laser Welded Blank Sheets
초록
In this paper, the forming limits of laser welded blank sheets are introduced, obtained from a tensile test and a hemispherical dome punch test. Especially, the forming limit diagram(FLD) on the heat affected zone with a width 2.54mm is emphasized. Also, the experimental experiences in finding specific strain conditions are discussed.
