Abstract
A method of non-destructively inspecting an adhesively bonded assembly of first, second, and third materials includes generating guided waves in the adhesively bonded assembly and establishing a dispersion curve plot in a first reference frame on the basis of receiving the guided waves. The method further includes comparing the dispersion curve plot with a plurality of reference dispersion curves established in the first reference frame, each of the reference dispersion curves being obtained by generating guided waves in a reference adhesively bonded assembly. Finally, the method includes estimating at least one of the thicknesses of the materials in the adhesively bonded assembly under inspection.
