Studies on Anisotropic Yield Characteristics and Press Formability of Metal Sheets : 4th Report, Investigation into Deep-Drawing

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
