摘要
本文首先对材料本构理论尤其是混凝土材料本构理论的研究现状进行丁评述,然后分析了混凝土的变形与损伤的物理机理及混凝土的几个重要而且特殊的本构现象,讨论了混凝土损伤、单侧受力特性、剪胀效应等的描述方法,最后介绍了几种混凝土损伤本构模型。
The state-of-the art of the research of constitutive theory for concrete is presented in this paper. Physical mechanism of deformation and damage of concrete and several important constitutive phenomena are analyzed. Descriptive methods to model damage, unilateral behavior and shear dilatation effect etc. of concrete are also discussed. Five damage constitutive models for concrete are introduced.
