Description

The verification of the adhesive bonds is one of the major problems in many fields. Different methods were suggested to check the quality of the bonds between a layer and a layer or a substrate. Most of these techniques are based on a spectral analysis of the acoustical signal reflected at normal incidence [1–5]. In this paper we focalize our attention on the analysis of the phase velocity dispersion curves characterizing the different samples and we suggest the use of these curves for checking the quality of the bonds.
