In this paper, the aperture change of the aluminum alloy aerospace structural parts under real load is researched. Static tests are carried out to simulate the load environment of flight course. Test results prove that, compared with the traditional methods, 3D digital speckle correlation method has good adaptability and precision on aperture change measurement, and it can accomplish non-contact, real-time measurement on 3D deformation or stress concentration.
