Nondestructive Inspection (NDI)

2021
This chapter discusses various nondestructive inspection () methods. Nondestructive inspection includes all methods to characterize a material without indenting, extracting samples, reducing its service capabilities or destroying it. The following chapter describes principles of NDI.

Tele-inspection Nondestructive Evaluation for Corrosion Applications

Materials Performance, 2023
Tele-manufacturing can accurately transfer skillsets from personnel to remote automation. Initially developed for hot work (e.g., tele-welding and tele-gouging), tele-manufacturing has been developed for inspection techniques usually performed manually by certified technicians.

Nondestructive inspection method

The Journal of the Acoustical Society of America, 1991
PURPOSE:To securely detect a defect even if a body to be measured is long by inputting an acoustic wave to one end of the body to be measured and analyzing transmission characteristics of the acoustic wave exiting from the other part on a frequency dependency frequency axis. CONSTITUTION:A transmitting transducer 2 is fitted to one end of the body 1 to

Nondestructive measurement for mango inspection

IEEE International Symposium on Communications and Information Technology, 2004. ISCIT 2004., 2005
This research aims to develop a dielectric property measurement system to classify and inspect dielectric objects (here mango). The moment method and geometric theory of diffraction are combined in the calculation process of inverse scattering measurement to improve accuracy.

Inspection uncertainty: The key element in nondestructive inspection

Nuclear Engineering and Design, 1977
Abstract This paper identifies the inspection uncertainty, which is a measure of the difference between the size of imperfection that has a high probability of being passed and the size of imperfection that has a high probability of being rejected by an inspection, as the primary measure of an inspection method, rather than the inspection sensitivity

Fatigue Reliability Analysis Using Nondestructive Inspection

Journal of Structural Engineering, 2001
In this paper, a comprehensive approach is developed to integrate computational reliability methods and nondestructive inspection (NDI) for fatigue reliability evaluation. Uncertainties existing in the performance and outcome of NDI are considered through numerical statistical measures, and the mathematical relationships among these measures are ...

Reliability analysis with nondestructive inspection

Structural Safety, 1997
Abstract Nondestructive inspection tools are commonly used to inspect structures or structural components with resistance deterioration due to defect size growth. The quality of the tools is mainly defined by the rate of detecting a defect with defect size s, ϱ(s), and the accuracy in sizing a detected defect.

Laser Based Nondestructive Inspection Techniques

Journal of Nondestructive Evaluation, 2012
The most familiar laser based optical nondestructive methods are based on the interference of the wave fronts of monochromatic light reflected from a test surface. We explore the origins, applications, advantages and limitations of these techniques with a journey through the realm of Holographic Interferometry, Electronic Speckle Pattern Interferometry
