金属薄板の降伏特性とプレス成形性 : 第4報,深絞り成形の検討

抄録

Based on Bassani yield function, a numerical analysis of axisymmetrical shrink-flanging is attempted, and the effect of anisotropic properties on the stress and strain distributions and the drawing force is examined. The Bassani function is found to be more useful to predict the strain distribution than Hill's conventional yield criterion. A parameter for estimating the formability of metal sheets in deep-drawing is proposed and its validity is confirmed experimentally.
