چکیده مقاله
Guided wave inspection systems are often used in low frequency–thickness ranges below the cut off frequency of the higher mode waves In this paper, the potentials of guided wave modes at higher frequencies are studied to inspect plate structures The wave propagation characteristics of high order wave modes and the corresponding sensitivity and detectability are investigated Using finite element based software, ABAQUS, the finite element simulations are employed to simulate the ultrasonic inspection system to simulate A0 and S0 wave mode distribution The FE based simulated inspection system is employed to evaluate the in plane and out of plane behavior of the A0 and S0 guided modes for a 1 mm steel plate at 2 5 MHz mm frequency
