In this paper we investigate whether the entropy of acoustic emissions (AE), can be used for determination of fatigue crack initiation and growth in AA7075-T6. The AE used for studying the damage evolution is acquired during fatigue testing of notched specimen under uniaxial cyclic load. The results show that the evolutions of the AE entropy estimated in… CONTINUE READING
