Abstract:With the increasing use of composite materials in modern structures, the defect detection of carbon fiber-reinforced plastics (CFRP) with ultrasonic waves is always a hot topic. Theoretical and experimental results demonstrate that the out-of-plane displacement of A 0 mode of Lamb waves is dominant at low-frequency ranges. Different types of defects including artificial defects, holes and cracks for flat plates, and artificial defects for a curved and stiffened (C&S)-CFRP plate are diagnosed. A shape compensat… 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.
