The present paper is devoted to the measurement of damage by resorting to image correlation techniques. This full-eld measurement procedure gives access to 2D and 3D displacements that can be utilized to analyze damage mechanisms, to estimate damage elds, and to determine material parameters of damage growth laws. Dierent features associated with image correlation are addressed in the context of continuum damage mechanics (CDM). Applications concerning damage detection, damage quantication and damage model validation are presented.
