【 摘 要 】

The deep drawing process is a forming process which occurs under a combination of tensile and compressive conditions. Formability is the ability of a given metal work piece to undergo plastic deformation without being damaged. The plastic deformation capacity of metallic materials, however, is limited to a certain extent, at which point, the material could experience tearing or fracture. Formability of sheet metal can be evaluated by various tests like swift cup drawing test, fukui's conical cup drawing test, erichsan cupping test, osu Formability Test, Hydraulic Bulge Test, Duncan Friction Test. These tests are widely used to evaluate of formability for different sheet metals. In this paper, swift cup and erichsen cupping tests presented.
