چکیده مقاله
Acoustic Emission AE technique is used to assess structural integrity For this purpose there is a need for discrimination of AE signals from fatigue crack growth and extraneous AE in order to quantitatively evaluate fatigue crack growth In this paper AE signals recorded during fatigue crack propagation in steel specimens are filtered and analysed First, AE signals are filtered for AE signals from fatigue crack activities Then, the results are analysed to separate AE signals from fatigue crack growth It is observed that less than 1% of all recorded signals are related to fatigue crack growth The results indicate that AE related to the peak load show reasonable correlation with crack growth rate Based on this correlation it may be possible to predict fatigue life
