摘要:
The influence of corrosion on ultrasonic and electromagnetic nondestructive evaluation results has been simulated for 2‐layer aluminum aircraft fuselage. Simulations have been performed with respect to ultrasonic time‐of‐flight measurements aiming on the detection of corrosion at the backwall of the first aluminum layer. Calculations of the eddy current probe response have been performed, where the thickness of the first and second layer and also the probe‐to‐specimen lift‐off at several eddy current operating frequencies have been varied. © 2003 American Institute of Physics
