Abstract
The influence of adhesive bond defects in multilayer structures on the spectra of acoustic pulses excited in them during inspection by the f ree-vibration and impedance methods is investigated. A notebook person al computer is used for spectral analysis and data processing. It is s hown that spectral processing enhances the sensitivity and reliability of inspection. The AD-64M computerized flaw detector has been develop ed on the basis of the reported investigations.
