N2 - Infrared thermography (IRT) inspections have become an accepted method for inspecting composite structures due to nondestructive and wider detecting area. In this study, a hybrid infrared image correlation method is proposed to measure the deformation of composite materials. The proposed method is based on performing a digital image correlation of the thermal images of specimen acquired under two different loads by step heating thermography. The thermograms of test specimens taken at different loads were processed to extract the bulk deformation from tiny changes in the thermograms using DIC. The DIC images were also taken by using visible light for comparisons. The digital image processing scheme developed, and its applicability are investigated and discussed.
