Abstract
The possibilities of strain measurements in composite structures using optical fiber strain sensors based on Bragg gratings are demonstrated. Specifics of interaction of the sensors with the environment were considered. Indications of optical fiber sensors can be used to predict mechanical behavior of composites structures as well as internal defects development based on numerical models. An approach to numerical modeling for identification of the most critical zones in terms of the appearance and development of delamination defects in polymer composite structures is proposed. Computational results for the case studies are presented.
