A technical report presents an assessment of the present capabilities and limitations of nondestructive testing (NDT) as applied to aerospace structures during the design, development, production, and operational phases. The assessment considers two material systems: (1) metal alloy systems and (2) bonded composites, such as honeycomb structures and fiber-reinforced composites. The NDT techniques discussed include radiography, ultrasonics, penetrants, and thermal, acoustic, and electromagnetic methods. Quantitative and qualitative data are presented in tabular form. No single source exists where the same information has been quantitatively treated. Reliability and standardization methods are presented, and corroborative data with fracture mechanics are given.
