Detection of Cracks under Installed Fasteners.
Abstract
The overall objective of this 2-year program was the development of a reliable nondestructive method of detecting cracks under installed fasteners, emphasizing improvement of the ultrasonic shear wave method. The program included the implementation of the developed method into a system suitable for on-line inspection of airplanes. The development effort proceeded in four main areas: ultrasonic fastener-hole scanning techniques, display of test information, identification of transducer requirements, and portable-scanner design.
