One of the crucial points in making materials with embedded optical fiber sensors is obtaining information about stress-strain state which helps to asses the influence of embedded optical fibers on integral mechanical properties of the structure and redistribution of stresses and strains in the area around optical fibers. In this paper models of woven composite material with embedded optical fibers are studied with numerical results achieved with the help of finite element method in case of GFRP VPS-33 material with fabric filler T-10-14 and epoxy resin ENFB-2M. Numerical results about the change of stiffness parameters of plate specimens in cases of tension and bending are obtained. Evaluation of stress state change near embedded optical fiber in different cases of optical fiber orientation with respect to loading and in the presence and absence of resin pocket defect with polyamide optical fiber coating taken into account is given in this study.

Distributed Optical Fiber

The present work is a comprehensive collection of recently published research articles on Structural Health Monitoring (SHM) campaigns performed by means of Distributed Optical Fiber Sensors (DOFS). The latter are cutting-edge strain, temperature and vibration monitoring tools with a large potential pool, namely their minimal intrusiveness, accuracy, ease of deployment and more. Its most state-of-the-art feature, though, is the ability to perform measurements with very small spatial resolutions (as small as 0.63 mm). This review article intends to introduce, inform and advise the readers on various DOFS deployment methodologies for the assessment of the residual ability of a structure to continue serving its intended purpose. By collecting in a single place these recent efforts, advancements and findings, the authors intend to contribute to the goal of collective growth towards an efficient SHM. The current work is structured in a manner that allows for the single consultation of any specific DOFS application field, i.e., laboratory experimentation, the built environment (bridges, buildings, roads, etc.), geotechnical constructions, tunnels, pipelines and wind turbines. Beforehand, a brief section was constructed around the recent progress on the study of the strain transfer mechanisms occurring in the multi-layered sensing system inherent to any DOFS deployment (different kinds of fiber claddings, coatings and bonding adhesives). Finally, a section is also dedicated to ideas and concepts for those novel DOFS applications which may very well represent the future of SHM.
