Abstract

This paper reviews the current state-of-the art Digital Image Correlation (DIC) technique as an improved tool for whole field strain measurements in the NDE of composite structures. Three case studies showing the full-field strains at stress concentrations in various composite structures are presented. These include composite overwrapped pressure vessels (COPVs) for space applications, composite repairs for commercial aircraft applications, and composite single lap bonded joints. The possibility of integrating DIC with state-of-art NDE techniques are also presented.
