文摘内容 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 prominsing way for the characterization of the cohesive quality in bonded plates。
