ABSTRACT
Ultrasonic guided waves have received considerable attention over the last decade from both a theoretical and experimental point of view. Emphasis is now on technology transfer to the field. Emphasis in this paper is focused on the inspection of aircraft components. Several problem descriptions and laboratory simulation studies will be presented. Reference to such basic topics as dispersion curves, wave structure and group velocity will be made. Sample inspection problems include fuselage wall thinning, lap splice, tear strap, composite patch repair, transverse cracking in helicopter blade assemblies, skin to core delamination in honeycomb structures, crack detection from bolt holes in the transmission beam of a helicopter, landing gear, cracks in the second layer, and hidden corrosion in multiple layer structures. Sample results will be presented along with aspects of test protocol development. © 2000 American Institute of Physics.
