| 摘 要： | 按照Valanis的理论,我们引进了一个新的内蕴时间量度。本文给出了适合于应变软化混凝土的内蕴时间非弹性本构关系以及混凝土的粘弹性本构关系。计算结果与实验比较表明本文结果能很好地与实验点相吻合。本文的两个本构关系在混凝土结构的断裂问题的分析中均是极为有用的。

| Abstract: | Following the theory of Valanis1], a new measure of intrinsic time is introduced.
The endochronic inelastic constitutive equation appropriate to strain-softening concrete and
the viscoelastic constitutive equation of concrete are given in this paper, The comparison
between the calculated results and the experimental data shows that the present results
can achieve the best fits of the experimental points. |
