Non-destructive testing of nuclear structures behind screen using leaky lamb waves
Résumé
The challenge is here to inspect a set of two or three parallel and immersed plates using leaky Lamb waves. The first plate(s) acts like a screen to be going through. The Energy Based Model (EBM) that has been validated in previous work is used here to study the forward propagation and the backward propagation after reflection on a defect. We found that it is possible to inspect a set of three parallel plates 7.8 mm thick and a set of two parallel plates 20 mm thick with pulse/echo configuration. Moreover, EBM predictions are in good agreement with in water experimentation results.
