Explain briefly five non-destructive material testing techniques
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and
industry to evaluate the properties of a material, component or system without
causing damage. The termsNondestructive
examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology. Because
NDT does not permanently alter the article being inspected, it is a highly
valuable technique that can save both money and time in product evaluation,
troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI),eddy-current testing, and low coherence interferometry. NDT is commonly used in forensic engineering, mechanical engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art.
