Abstract:Abstract. The mark-tracking method was used in the uniaxial tensile test to determine the elastic properties of optical fibers. The mark-tracking method is based on the followup of two markers on the specimen with the help of an image processing technique. It allows us to determine the true strain with respect to the small strains assumption (e≤1%) or the finite strains (e>1%) without any impact of the rigid solid movement neither pulley fiber sliding on the measured strain. Optical fibers used in this study a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
