Flexural Wave Propagation Characteristics of Lattice Sandwich Plates

Abstract:

This paper is aimed to study flexural wave propagation characteristics of lattice sandwich plates. Based on Blochs theorem, band structure of flexural wave propagation in the plate is obtained by commercial finite element software Comsol Multiphysics. Meanwhile, frequency response is obtained and its maximum attenuation is exactly corresponding to the band gaps. Finally, effects of lattice pattern on band gaps are introduced.
