摘要：

A simple simulative test was developed to evaluate the stamping formability of steel sheets in plane strain stretching deformation. The stamping formability was evaluated by the limiting punch height (LPH) value in the plane strain punch stretching (PSS) test compared to the minimum of the limiting dome height (LDHo) value in the hemispherical punch stretching test, the standard LDH test. The PSS test shows a stable plane strain deformation and a good reproducibility with less scattering data. Moreover, the LPH value in the PSS test ranks well the stamping formability of various sheet materials and shows good correlations with press performance.
