摘　　要：1993年希尔提出了一个适用于正交各向异性材料的屈服准则 ,该文运用该屈服准则和马辛尼克 库祖斯基假设 ,建立了能够确定正交各向异性金属板料成形极限的控制方程并数值求解 。A new yield criterion applied to the orthotropic materials was proposed by Hill in 1993. In this paper, the governing equation which predicts the forming limits of orthotropic sheet metals is presented and is sloved numerically by using the yield criterion and the Marciniak Kuczynski hypothesis. The effects of various material parameters on the forming limit diagrams are analysed.
