摘要
损伤本构关系的研究是混凝土力学性能研究的重要内容,从损伤本构关系确立的过程入手,给出了损伤变量的选取、损伤变量的演化规律及损伤模型的确立三方面内容。主要针对弹性、弹塑性本构模型分类进行阐述,对比各损伤本构模型的不同和优劣,总结了混凝土宏观损伤本构的研究进展,为混凝土宏观损伤本构关系研究提供思路。
The research of damage constitutive relation is an important part of concrete mechanical properties study. From the general process of studying the constitutive relation of damage,three aspects of the selection of damage variable,the evolution law of damage variable and the establishment of damage model were given. The elasto-plastic constitutive model classification was mainly described. The differences and advantages and disadvantages of the damage constitutive models were compared. The development course of the macroscopic damage constitutive structure of the concrete was summarized and the ideas for the macroscopic damage constitutive relation of the concrete were provided.
