Abstract: Digital image correlation (DIC) is a widely employed technique to study deformation of fiber-reinforced composites at the macro and meso-levels. It is, however, rarely applied at the micro-level although deformation analysis of the microstructure is of great interest in the field of composites. This is mainly attributed to practical difficulties related to creation of a nano-scale speckle pattern as well as the experimental set-up. The challenge is to combine DIC with SEM, where imaging involves noise, the gray intensity level of microstructure can be uniform over large areas, and it is difficult to maintain the observation window fixed during loading.
