    Abstract

    Relationships between the characterization and the nondestructive detection of fatigue damage are discussed and illustrated. Inspection methods presently used at overhaul facilities are reviewed, and examples of the equipment used and the results obtained are given. The advantages and limitations of currently used nondestructive methods are summarized. A perspective review of recent research efforts in nondestructive fatigue damage detection including descriptions of methods and typical experimental results is presented. Finally, nondestructive evaluation technology is appraised critically in relation to the desired results and practices, and this appraisal is used as a basis for a look into the future.
