In this paper, a honeycomb sandwich beam and a plate are studied to verify a method of determining the equivalent properties of these structures. The responses of the structures are obtained from both numerical and physical experiments considering free-free boundary conditions. It is shown that a double-layer effect caused by the bonding-stretching process during manufacturing cannot be ignored. It is also found that at low frequencies, the equivalent method gives good agreement with measurements. However at higher frequency range, the response calculated using equivalent method shift towards higher frequency compared with measurements.
