| Abstract: | Acoustic emission (AE) behaviors of steel wire have been studied firstly during high- cycle fatigue damage. Results showed that AE process consists of three distinct stages, corresponding to plastic deformation, fatigue crack nucleation and crack propagation, respectively. It can be seen from this that the period of fatigue crack nucleation and initiation was approximately 70% of entire fatigue life, and that of crack propagation was only 30%. |
