Experimental Investigation on Forming Limit of Laser Welded Blank Sheets
레이저 합체박판의 성형한계평가 실험에 관한 연구
Abstract
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.
