Abstract

In this paper, digital micro-speckle correlation method is used to calculate strain field of functionally gradient material (FGM) in constant temperature, and the results are compared with that of double layer material in constant temperature. This paper offers a kind of feasible experiment method and meaningful results to design and prepare functionally gradient material. The experiment shows that the FGM can relax effectively the stress between any two laminates.
