#ndt Non-destructive testing (NDT) is a way to detect and evaluate flaws in materials. Within aerospace NDT plays a vital role in the design, manufacture and maintenance of aircraft.

The simplest and most accurate way of testing materials and components is often to test them to destruction. Destructive testing is used in aerospace to determine the physical properties of materials, components and assemblies. It can reveal useful information about characteristics of materials including ductility, tensile streng
