Guided Lamb Wave Propagation in Composite Plate/Concrete Component
Publication: Journal of Engineering Mechanics
Volume 128, Issue 12
Abstract
This research examines the propagation of guided Lamb waves in fiber-reinforced polymer (FRP) bonded components, establishing the effectiveness of combining laser ultrasonic techniques with a time frequency representation (TFR) to experimentally measure the dispersion curves of a concrete component repaired with a FRP plate. A TFR is used to operate on experimentally measured, guided Lamb waves to resolve a FRP bonded component's individual modes and generate its dispersion curves. The objective of this research is to demonstrate that it is possible to develop the dispersion curves of FRP bonded components from a single, experimentally measured guided Lamb wave. The experimental results show that the stiffer the bond, the more deviation from the behavior of a free plate specimen, and the less modes that are present.
