Free vibration analysis of sandwich beams with foam-corrugated core
Abstract eng: Summray The vibration performance of foam-filled corrugated sandwich beam was investigated in this paper. Based upon a micromechanics-based model, the effective elastic constants of foam-filled corrugations are derived by the homogenization method. It is used to predict the natural frequencies and vibration modes of the sandwich beam. In order to validate the equivalent model, model testing under clamped-free boundary conditions was carried out. The results using a homogenization method show good agreement with experimental tests.
