| Abstract: | This paper mainly discusses the application of AE (acoustic emission) on fatigue crack propagation. According to the signal feature of fatigue crack propagation and its testing situation,choose the appropriate dictation method of fatigue crack propagation. And combining with the experimentation on test machine of fatigue crack propagation,we can obtain the superiorities in the application of AE on fatigue crack propagation. |
