Non-destructive Testing and Damage Detection

This chapter briefly describes various techniques used for non-destructive inspection (NDT) of aerospace components for detecting defects, cracks, corrosion, and other degradation features, as part of quality assurance and in-service inspection. The capabilities and applications of widely used NDT techniques for examining metallic as well as composite aerospace structures are discussed. Recent advances in NDT techniques for automated, fast and cost-effective in-service and in situ monitoring of aircraft are highlighted, as well as future directions.
