Thickness measurement in composite materials using lamb waves viscoelastic effects.
Pulse propagation in plates has been investigated with the identification of Lamb modes. The application of this technique to the measurement of thickness in composite and coarse materials was previously evaluated. As a sequel, results of the application of this technique taking into account the viscoelastic properties of PVC and ferrocement are presented.
