Abstract

Digital imaging techniques are often useful to measure bidimensional surface displacements and deformations. One of these techniques is the digital image correlation which correlates digital images of speckle patterns to calculate displacements and strains. In this work is presented the application of digital image correlation to the analysis of the local behaviour under load of composite materials. Applications of the technique to numerically generated digital images, useful to evaluate globally the technique, are also reported.
