Abstract EN
The damage process is accompanied by the acoustic emission for quasibrittle materials.
And in the process of material damage evolution, the length of microcracks satisfies the fractal distribution.
Research on their relationship in theory is helpful to reveal the law of material damage evolution and acoustic emission activities.
Damage variable expressions are proposed based on the damage and fractal characteristics firstly.
Then, the statistical models for acoustic emission considering damage and fractal characteristics are established by deducing the relationship between acoustic emission parameters and load cycles and fractal dimensions.
The effects of damage and fractal effects on acoustic emission parameters are analyzed finally.
The results show that the damage accelerates the AE activity to the rougher material, the opposite to the more homogeneous material.
It can also be seen that the increase of the fractal dimension, the homogeneity constant m, will substantially increase the AE activities.
