Journal ArticleDOI
Identification of failure modes in glass/polypropylene composites by means of the primary frequency content of the acoustic emission event
TL;DR: In this article, a tensile test was carried out on glass/polypropylene specimens made in-home, and acoustic emissions were recorded from these tests, and the hypothesis is that each micro mechanical event will have one distinctive waveform as fingerprint.
Journal ArticleDOI
The use of broadband acoustic transducers and pulse-compression techniques for air-coupled ultrasonic imaging.
TL;DR: Capacitance transducers were used to generate wide bandwidth swept-frequency signals in air, which were then used to measure and image solid samples in through transmission, demonstrating that such signal processing techniques lead to an improvement in the signal to noise ratio and timing accuracy for air-coupled testing.
Journal ArticleDOI
Determination of the combined vibrational and acoustic emission signature of a wind turbine gearbox and generator shaft in service as a pre-requisite for effective condition monitoring
TL;DR: In this paper, a review of current progress in condition monitoring of wind turbine gearboxes and generators is presented, as an input to the design of a new continuous condition monitoring system with automated warnings based on a combination of vibrational and acoustic emission (AE) analysis.
Journal ArticleDOI
Inspection and Structural Health Monitoring techniques for Concentrated Solar Power plants
Mayorkinos Papaelias,Liang Cheng,Maria Kogia,Abbas Mohimi,Vassilios Kappatos,Cem Selcuk,Louis Constantinou,Carlos Quiterio Gómez Muñoz,Fausto Pedro García Márquez,Tat-Hean Gan +9 more
TL;DR: In this article, non-destructive evaluation techniques that can be employed to inspect solar receivers and insulated pipes as well as relevant research and development work in this field are discussed, and a discussion of the nondestructive inspection of solar receivers can be found.
Journal ArticleDOI
An experimental study of acoustic emission methodology for in service condition monitoring of wind turbine blades
TL;DR: In this article, the authors investigated the feasibility of in-service monitoring of the structural health of wind turbine blades by acoustic emission (AE) monitoring, which was performed over periods which totalled 21 days, during which AE monitoring was performed with a 4 sensor array.
