The fatigue cracks of aircraft skin which are caused by the pressurization for a civilian airplane during the flight process will bring potential serious safety risks. Therefore, it is necessary to study the deformation mechanism for the aircraft skin on uniform pressure. Traditional fatigue testing machines can only be used for simple tension and compression tests which cannot be applied directly. This paper proposes a deformation detection method by using speckle image correlation technology. Firstly, a fatigue testing machine simulating uniform pressure has been designed. Secondly, a speckle image correlation method by using improved KLT (Kanade-Lucas-Tomasi) algorithm is presented to obtain the coordinates of the coated speckle spots. Finally, static and dynamic experiments were implemented to verify the accuracy and effectiveness of the proposed method. In conclusion, this method can be applied in airworthiness certification to improve the testing efficiency.
