Research results show that: 1 The FLSD is basically path independent whether is for steel or for aluminium; 2 Shape of the forming limit curve in stress space is sensitive to the type of material model used in transformation form FLD to FLSD; 3 the anisotropy of sheet metal has considerable influence on the FLSD; 4 The application of the FLSD in sheet metal processes optimization was considered to be effective and more precise.

钢板和铝板应该分别采用不同的材料模型进行转换。3）板料各向异性性能对板料成形极限有影响，在使用FLSD时应该考虑板料的各向异性情况；4）FLSD在应用于多道次成形零件的有限元分析时，由于其具有的与加载路径无关的特点，因此比通常用的FLD更加准确可靠。本课题的研究为以后在板料成形仿真中，使用应力成形极限曲线代替应变成形极限曲线，提供了理论和试验依据。
