Abstract: As a practical and effective tool for surface deformation measurement, digital image correlation (DIC) technology has been widely accepted and increasingly used to measure the deformation and damage behavior of composite materials. Composite materials have the properties of non-uniformity and anisotropy, which lead to complex deformation behaviors after being loaded. Traditional measurement techniques cannot accurately capture these behaviors due to various factors. As an advanced optical measurement technology and means, DIC has significant advantages in measuring the deformation behavior of composite materials. The principle of DIC and the factors that affect measurement accuracy are described in detail. Then, the application of DIC in deformation measurement and damage characterization of composite materials is mainly introduced. Finally, the possible development direction of DIC in the future is prospected.
