TITLE: Enhancement of ultrasonic Lamb wave transfer to fiber Bragg grating sensors through remote bonding

ADVISOR: Dr. Kara Peters

DATE & TIME: Thursday, October 11, 2018 at 3:30 PM

LOCATION: EB3 – 3115

 

ABSTRACT:

Fiber Bragg gratings (FBGs) are often utilized as transducers to detect ultrasonic waves for structural health monitoring (SHM) applications. However, the extraction of relevant features from the measured ultrasonic Lamb waves requires a high signal-to-noise ratio. This research demonstrates enhancing the ultrasonic detection sensitivity of an FBG through remote bonding of the FBG and examines the conditions at which the enhancement occurs.

 

BIOGRAPHY:

Junghyun Wee received the B.S. degree in Mechanical Engineering from both the State University of New York at Stony Brook and the University of Seoul through the dual degree program in 2013. In 2014, he joined the combined M.S./Ph.D. program in Mechanical and Aerospace Engineering at North Carolina State University. He has been studying in the Smart Composite Laboratory under the guidance of Dr. Kara Peters.
