用立方晶系多晶金属板的ODF数据计算R值的模型探讨

ON THE MODEL OF CALCULATING R─VALUE BY USEING ODF OF CUBIC POLYCRYSTALIC METALLIC SHEET

选用非平方屈服函数，在混合模型（ｋｏｃｈｅｎｄｏｒｆｅｒ模型下），直接用ＯＤＦ数据计算了立方晶系多晶金属板材的Ｒ值。

By using non─square yield function,R─value of cubic polycrystalline metallicsheet has been calculated using kochendofer model. In calculation,ODF is directly used。
