Novel hydrophilic polymer couplant for application in ultrasonic non destructive testing [PDF]

open access: yes, 2001
Ultrasonic Non Destructive Testing (NDT) is used to inspect materials and structures for defects. Water is commonly used in NDT as a couplant to improve ultrasonic transfer between an interrogating probe and test piece.

New Developments in Ultrasonic NDT Modeling in CIVA [PDF]

open access: yes, 1998
In quantitative ultrasonic nondestructive testing (NDT), modeling the forward problem is an essential step forward for interpreting experimental data, the ultimate goal of NDT. Both numerical or approximate methods are developed. They do not fulfill the same requirements.
