An experimental method to visualize the propagation of ultrasonic Lamb waves in composite plates with delaminations, using air coupled ultrasonic transducers, is described here. Using this method experiments are done, on glass fiber reinforced plastic(GFRP) laminates, to study the Lamb wave interactions with delamination type defects. The S 0 and A 0 modes are chosen for experiments at an excitation frequency of 200 kHz. Defect dimensions are calculated from the visualization images and compared with actual values. A method for detecting depth of defects using deviation of wave-fronts, at the defect contours, is presented.

“…The importance was highlighted by the accident at the Monju reactor [13] which resulted in a sodium leak. Since then, there have been a number of studies reporting experiment based programs to establish and evaluate under-sodium viewing capability [14][15][16][17][18][19][20][21][22][23][24][25][26].…”
