Nondestructive Testing (NDT)

open access: gold, 2021
Nondestructive testing (NDT) refers to the science and technology of non-invasive methods of testing, evaluation, and characterization of materials, components, or systems without impairing their performance and serviceability. It provides techniques to detect and characterize flaws in materials and structures and plays an important role in the ...
