^Experimental Study on Acoustic Emission Process and Its Self-Similarty of Concrete Material

摘要: 将对材料声发射的研究同对力学过程的研究、材料断裂损伤等破坏过程的研究相结合,提出了声发射过程的概念。在此基础上,进一步给出了定量考察声发射过程自相似性的自相似特征函数.测试结果分析表明,混凝土试块在单轴压缩过程中,声发射过程的自相似程度随着应力状态的变化而变化.Abstract: The study on acoustic emission (AE) of concrete material is combined to the studies on mechanical process and fracture damage, and the conception of AE process is put forward. On this basis a quatitative function for analysing the self-similarity of AE process has been developed.The experimental results show that the values of the self-simi-larity function of the AE process in concrete material vary with the state state during uniaxial compression.
