题目：Concrete damage constitutive relation based on characteristic parameters of acoustic emission

作者：Jun Lu, Shaowei Hu, Xiangqian Fan

Abstract: Based on the experiments, the parameters of acoustic emission signals were discussed about cracks, expansion and instability of concrete in this paper. The relationship between different acoustic emission signals of concrete were established on damage constitutive relation. A new method was provided by damage assessment for hydraulic structures.

Keywords: Concrete; acoustic emission signals parameters; damage constitutive relation
