关于应变Lode参数的研究

THE RESEARCH ON LODE PARAMETER OF STRAIN

本文从塑性应变Ｌｏｄｅ参数着手深入研究了应变Ｌｏｄｅ参数即中间主应变与各应变参量间的内在联系，给出了相应数学表达式。本文首次引用相对应变莫尔圆的概念并确定了该相对应变莫尔圆的变化范围。对塑性理论应变分析及应用具有重要意义。

tarting with Lode parameter of plastic strain,this paper has studied inherent relate of Lode parameter of strain(second main strain)and each strain parameter in depth,gived appropriate mathematics expression.This paper quotes conception of relative Mole circle of strain for the first time and defines its variation extent,has important significance its applicatoin.
