混凝土材料在单轴拉伸时的声发射机理探讨

Approach to Acoustic, Emission Mechanism of Concrete in Uniaxial Tension

在实验基础上，根据断裂力学理论对混凝土材料在单向拉伸状态下不同变形阶段的声发射机理进行了探讨，所得结论与实验相吻合，从而为声发射技术在混凝土材料的稳定性评价及损伤预报方面的应用提供了理论依据．

The acoustic emission mechanism of concrete at different stages in uniaxial tension was studiedexperimentally on a basis of frature mechanics. The conclusions reached was in conformity with experimentalresults. This will provide a theoretical basis for tile stability evaluation and damage prediction of concrete.
