LTRASONIC AND ADVANCED METHODS FOR NONDESTRUCTIVE TESTING AND MATERIAL CHARACTERIZATION

NDT Ultrasonido

Descripción

For over sixty years, the nondestructive testing (NDT) or nondestructive evaluation (NDE) of materials has been an area of continued growth. The need for NDT has increased dramatically in recent years for various reasons such as product safety, in-line diagnostics, quality control, health monitoring, and security testing, etc. Besides the practical demands the progress in NDT has a lot to do with its interdisciplinary nature. NDT is an area closely linked to aerospace engineering, civil engineering, electrical engineering, material science and engineering, mechanical engineering, nuclear engineering, petroleum engineering and physics among others. There are at least two dozen NDT methods in use. In fact any sensor that can examine the inside of material nondestructively is useful for NDT. However the ultrasonic methods are still most popular because of its capability, flexibility, and relative cost effectiveness. For this reason this book places a heavy emphasis on the ultrasonic methods which are covered in Part I of the book.
