塑性本构关系的应变路径理论
Strain Path Theory of Plastic Constitutive Relation
-
摘要: 基于伊留申的两个假定,提出一个新的积分形式的塑性本构方程.由应变路径确定的应力偏量由二部分组成,它们各自按不同的规律变化.理论计算与近代实验的比较,得到令人满意的结果.本文提出的不是内时理论.Abstract: Based on Illiushin's two hypotheses,a new plastic constitutive equation of integral type is proposed.The devialoric stress induced by a strain path consists of two parts which vary according to different laws.Comparison of theoretical calculation with recent experiments is satisfactory.The present theory is not an endochronic theory.
