Abstract

Guided waves are applied for subsurface damage detection in the structure of a composite skin on a half-space. The global matrix method with a 2D root search is used to determine the complex wave numbers. The dispersion relations and wave structures are obtained for both propagating and attenuating modes in which the attenuation is caused by the leakage from the waveguide to the half-space. The scattering of leaky waves by skin-substrate disbond is analyzed by a finite element model. Theoretically driven experiments are conducted on a composite rotor blade section to detect the disbond between skin and substrate.
