摘　　要：在薄板成形过程中需要精确地描述薄板的各向异性特征。本文给出了用三参数Ｂａｒｌａｔ－Ｌｉａｎ各向异性屈服函数有限元数值模拟盒形件拉深过程的结果，给出了各向异性系数Ｒ对耳状法兰边的形状影响及成形高度，厚度变化，薄板法兰边起皱等结果，并与实验结果进行了比较，结果是令人满意的。Model of sheet metal forming processes requires an accurate description of anisotropic material behaviors.This paper describes the finite element(FEM) simulation results obtained by using Barlat-Lian tricomponent anisotropic yield function for cup deep-drawing test.Earing profiles、cup height and wrinkling of flange are computed.Earing formation are compared for different R values.Good agreement was found between FEM simulations and experiments.
