关于混凝土中微裂缝的形成机理与宏观力学行为的初探

The Elementary Investigation on Crack-Nucleation Mechanism and Mechanical Behavior for Concrete

对混凝土内部微裂缝的形成机理及其控制因素进行了较为系统的分析讨论，并对混凝土单轴受力时非线性力学性能作了初步的探讨，提出混凝土的细现缺陷的形成机理及其宏观非线性力学性能的研究将对混凝土结构设计理论和方法产生深远影响。

In this paper, the crack-nucleation mechanism and dominating factors were systematically investigated. And the uniaxial non-linear curves of stress-strain tested by different experimental methods were analyzed. Then, the relationship between growth and macroscopic mechanical behavior was discussed. The results show that the non linear mechanical study including microscopic defects is very important for the design theory of concrete structure.
