| Abstract(E) | In this study, the natural vibration response of lightweight sandwich beam with lattice core has been investigated numerically by using the finite element method and analytically based on the Rayleigh-Ritz method. The lattice core discussed in this study were manufactured by our in-house metal 3D printer. In particular, the effects of micro-architecture of the lattice core on the vibration behavior were discussed. The obtained results were compared with experimental results conducted by using the impulse force hummer, and the prediction accuracy of the vibration frequency was discussed. |
