Abstract

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.
