...Abhijeet Kumar; Sauvik Banerjee; Anirban Guha Debonding between stiffener and base plate is a very common type of damage in stiffened panels. Numerous efforts have been made for debonding assessment in the stiffened panel structure using guided wave-based techniques. However, these studies...

... core is frequently damaged during production and operation, even if the damage is not visible on the face-sheet. In this study, an ultrasonic-guided wave (GW) propagation technique is utilized for robust and reliable nondestructive evaluation of a honeycomb composite sandwich panel (HCSP...

...Andrew Downs; Ronald Roberts; Jiming Song An important advantage of guided waves is their ability to propagate large distances and yield more information about flaws than bulk waves. Unfortunately, the multi-modal, dispersive nature of guided waves makes them difficult to use for locating flaws...

... monitoring methods, piezoelectric transducer (PZT) network and guided wave-based imaging method has proved to be an effective structural health monitoring (SHM) technology. However, the pursuit of accurate localization of ordinary impact imaging methods comes at a cost, the high requirement for the SHM...
