the damage evolution to acoustic emission parameters was proposed by incorporating the AE rate process theory. The AE monitoring results indicate that damages occur in both elastic and plastic phases... of steel strand.Key words:acoustic emission; rate process theory; steel strand; damage evolution model; surface friction......
