Abstract
The objective of the present work is to study the effect of debonding damage on the modal damping of a sandwich panel. The experimental FRF, obtained with a broadband excitation, were already available from an analogous research concerning the variations of resonant frequencies. For some modes the results have shown that increasing in severity of damage cause a slight increase in damping coefficient. Finally comparisons between the variations of modal damping and frequency is performed.File allegati a questo prodotto
