Ultrasonic System Measures Elastic Properties Of Composites

TLDR: In this paper, an ultrasonic transducers operating in pitch/catch mode excite and detect leaky Lamb waves in specimen and characterize elastic properties of specimen and defects within it characterized from dispersion curves of Lamb waves.

Abstract: Measurements with leaky Lamb waves yield data on properties and defects of panels. System nondestructively measures elastic properties of, and defects in, panel of laminated fiber/matrix material. Ultrasonic transducers operating in pitch/catch mode excite and detect leaky Lamb waves in specimen. Elastic properties of specimen and defects within it characterized from dispersion curves of Lamb waves.
