Damage Detection using SONIC IR Imaging for Composite Laminate


Abstract Non-Destructive Testing (NDT) is a branch of scientific methods and techniques

used to evaluate the defects and irregularities in engineering materials. These methods

conduct testing without destroying or altering material’s structure and functionality. Most

of these defects are subsurface making them difficult to detect and access.

SONIC INFRARED (IR) is a relatively new and emerging vibrothermography

method under the category of NDT methods. This is a fast NDT inspection method that

uses an ultrasonic generator to pass an ultrasonic pulse through the test specimen which

results in a temperature variation in the test specimen. The temperature increase around

the area of the defect is more because of frictional heating due to the vi... (more)
