Multi-type damage localization using the scattering coefficient-based RAPID algorithm with damage indexes separation and imaging fusion

Qiao Bao,
Tian Xie,
Weiwei Hu
et al.

Abstract: Guided waves-based structural health monitoring (SHM) methods have potential for practical applications, since they are sensitive to small damages and are able to realize large area monitoring. Among these methods, the Reconstruction Algorithm for Probabilistic Inspection (RAPID), using a Piezoelectric transducer (PZT) sensor array, is one of the most widely used imaging algorithms to perform active damage monitoring and localization. However, since the sensing paths are distributed inside the sensor array wit… Show more

“…In recent years, various novel damage imaging methods have been developed to visualize damage and quickly locate anomalies. Noteworthy among these imaging 2 methods are the elliptical imaging algorithm [6], the time reversal (TR) algorithm [7], the reconstruction algorithm for probabilistic inspection (RAPID) algorithm [2,8], the multiple signal classification (MUSIC) algorithm [9] and the delay-and-sum (DAS) algorithm [10]. Each of these imaging methods was designed for distinct applications.…”
