Abstract
Ultrasonic guided waves can be generated with great penetration power into a variety of structures including containment structures that are inaccessible by other nondestructive testing (NDT) techniques. The containment structure discussed is a plate partially coated with thick concrete. A transducer is placed near an end section of the plate to produce guided waves in the plate. Anomaly echoes are then received. Several kinds of guided waves including shear horizontal and lamb wave modes were studied in terms of energy leakage, sensitivity and testing reliability. Experimental results show great sensitivity for the anomalies and great penetration ability into the concrete coated plates despite the concrete covering.
