Lock-in thermography is a well-established non-destructive technique for detecting damage
in composite materials. The success of the lock-in technique in industrial applications …

This work describes the implementation of an eddy current sensor for the non-destructive
testing of damage of carbon fiber-reinforced polymer (CFRP) composite materials. The …

Carbon fiber-reinforced composite hydrogen storage cylinder is a key component used in
hydrogen fuel cell electric vehicles. However, some micro defects such as voids and …

Aluminum skin honeycomb sandwich panels (HSPs) are commonly used in aerospace
structures. Conventional contact-based detection methods may scratch the skin surface or …

The application of Background-oriented Schlieren (BOS) technology for measuring air flow
temperatures is becoming increasingly popular due to its simplicity and practicality …

This paper provides an extensive discussion of a complex amplitude-based dynamic three-
dimensional deformation measurement method, in which the phase and amplitude of the …

Fringe patterns are typically produced as the results of traditional optical Nondestructive
Evaluation (NDE) employing digital shearography. Structural flaws affect the response of the …

Long pulse thermography (LPT) and shearography have been developed as primary
methods for detecting debonding or delamination defects in composites due to their full-field …

Honeycomb sandwich panels are utilized in many industrial applications due to their high
bending resistance relative to their weight. Defects between the core and the facesheet …

Shearography, an effective non-destructive testing tool, is widely employed for detecting
defects in composite materials. It detects internal defects by detecting deformation …
