Theory and Practice of Nondestructive Testing
Theory and Practice of Nondestructive Testing. Instructor: Prof. Ranjit Bauri, Department of Metallurgical and Materials Engineering, IIT Madras. Nondestructive Testing (NDT) plays an extremely important role in quality control, flaw detection and structural health monitoring covering a wide range of industries. There are varieties of NDT techniques in use. This course will first cover the fundamental science behind the commonly used NDT methods to build the basic understanding on the underlying principles. It will then go on to cover the process details of each of these NDT methods.
