Basics of Structural Defect Detection

Non-destructive testing (NDT), also sometimes referred to as non-destructive evaluation (NDE) or non-destructive inspection (NDI), is a manner of testing products in a way that leaves them fully functional afterward. Contrast this with destructive testing, for example a strength test, in which a product is taken to an ultimate failure load to determine its ultimate breaking strength. If we need to test 100% of, or even a large portion of, a group of products we want to have the parts remain functional after the test is completed. We need a non-destructive test method. Fortunately, the NDT industry provides us many non-destructive test methods that each provide various types of information about a product being tested.
