다국어 초록 (Multilingual Abstract)

In the deep drawing of sheet metal the defects such as wrinkling, folding and tearing should be eliminated by properly designed tools. The draw beads are especially one of the most important elements in the control the material flow and thus the product quality can be dependent on the shape and location of the draw-beads in the sheet metal forming process.
In this study, arc draw-bead has been introduced in order to investigate the material flow in deep drawing of cup with hemisphere bottom profile semi-spherical shaped vessel using rectangular initial blank. The shape of draw-bead is circular type and its main purpose is to delegate the material flow in the four sides of the square blank. Minimization of the waste material of the initial blank can be accomplished by using proper location and shape of arc draw-bead. DEFORM-3D commercial software is used for FE analysis in the deep drawing of hemisphere cup with spec sheet material.
