3-D FEM Analysis of Forming Process for Laser Welded Blank Considering Welded Zone
용접부를 고려한 레이저 합체박판 성형공정의 3차원 유한요소 해석
Abstract
The finite element formulation is developed for predicting strain distributions and weld line movements in the forming processes of laser welded blank. The welded zone(WZ) is modelled with several narrow finite elements whose material characteristics are analytically obtained from those of base metals based on the tensile tests. In order to show the reliability and effectiveness of weld element the forming process of hemispherical dome stretching and auto-body door inner panel stamping are simulated FEM predictions show good agreements with experimental observations.
