摘要

A digital image correlation method is presented in this paper. This non-contact technique can be used in many applications to measure the displacement and strain fields. Like the speckle method, it uses the digital image correlation principle but it is much simpler to use. In fact, a set of pixels, called pattern, in an initial image is directly compared to the pixels of the final image. The accuracy of displacement measurement could reach 1/60th of a pixel. Treatment of two images with large strain (≈ 100 %) is possible. Very accurate cartography of strain field is obtained with this method. The covered field can range from few square millimetres to few square metres. The measurement of the stress intensity factor K1 for thin sheets of copper is given as example in this paper.
