Composite materials have mechanical behavior comparable to metallic alloys, with the benefit of being lighter. However, due to their anisotropy, integrity characterization of impact damages remains a challenge. Non-Destructive Testing (NDT) methods a

High subjectivity, lack of attention and fatigue are factors inherent to human analysis in inspection activities such as shearography, a non-destructive optical method. In order to minimize the probability of human error, a study was conducted in whi
