Acoustic emission evaluation method in bond-slip test
The paper expounded the application of acoustic emission(AE)technology in bond-slip test.Firstly was used wavelet packet signal analysis technology to decompose and synthesize the AE signals during the bond-slip process.After that,the method of cross-correlation was applied to the synthesized signals to locate the source.Then,through the characteristics of AE signals to study process of bond-slip process.Lastly the AE evaluation method for the macroscopic fracture of bond was analyzed and summarized.
