Earlier studies based on analysis of surface wave (Rayleigh waves or Scholte waves) are not really adapted to the characterization of such surfaces. Guided acoustic waves, i.e. Lamb waves, turn out to be the best adapted kind of waves to characterize this roughness when plates are bounded together. It is the aim of this paper to provide analytical and experimental approaches to analyse the behaviour of Lamb waves propagating inside plates with a rough surface (small perturbations). Firstly experimental results of the attenuation effects are given on roughened glass plates; secondly the attenuation factor of the Lamb wave in an anisotropic rough solid plate is calculated through a complex analytical model of the dispersion equation which accounts for the effect of the Power Spectrum Density (PSD) of the rough profile (including the effect of the statistical roughness parameters).Show less >
