Abstract: The aim of this study is to evaluate the effect of debonding on the vibration characteristics of the sandwich panel. The studies were carried out on rectangular flat sandwich panels made of thin aluminum sheets and a honeycomb core. The effect on natural frequencies and the mode shapes of the debonding at different sizes were numerically investigated by the finite element model. The results show that the debonding reduces the natural frequencies of the sandwich panels, however, a small debonding region has little effect, especially on the lowest mode of vibration. The decreasing of the natural frequencies increases disproportionately when the debonding size extends beyond the critical value. The results can be helpful for assessing the effects of debonding and can be used for non-destructive evaluations of the damage to sandwich panels from vibration characteristics.
