The paper presents the results of Acoustic Emission (AE) testing of fatigue fracture initiation
and propagation in metal plates. The information Entropy of the AE data (ie, AE Entropy) is …

The paper presents an innovative approach for structural health monitoring of metallic
components under fatigue crack phenomena. The methodology is based on the evaluation …

Acoustic emission (AE) is a passive nondestructive testing (NDT) technique which is
employed to identify critical damage in structures before failure can occur. Currently, AE …

Featured Application The work presented in this paper outlines three methods to analyze
individual acoustic emission waves emitted within a cyclically-loaded metallic structure …

Sensitive structures, such as airframes, need careful inspection and maintenance to avoid
fatigue failures. These activities are expensive, discrete and imperfect, since catastrophic …

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 …

An important objective of acoustic emission (AE) non-destructive monitoring is to accurately
identify approaching critical damage and to avoid premature failure by means of the …

In this paper, we propose the information entropy of acoustic emission (AE) signatures as an
index for assessment of degradation in materials. This is a new method for health monitoring …

This paper reports experimental estimation of the relative entropy associated with acoustic
emission obtained in the course of the fatigue degradation of the Al 7075-T6 specimens. A …

Acoustic emission (AE) as a non-destructive testing technique is used to identify structural
fatigue damage through the evolution of AE characteristic parameters, aiming to prevent …
