Abstract ： The two-layer normal mode expansion method is employed to analyse the laser-generated elastic guided waves in bonded plates accounting for the adhesive bond layer in terms of a weak interface with the spring model. The sensitivity of dispersion and transient characteristics of the guided wave to the stiffness coefficients characterizing the cohesive quality is analysed in details. This method provides a new promising way for the characterization of the cohesive quality in bonded plates.
