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.

Flexural Wave Propagation

Plate equations for the incremental deformation in composite plates with orthotropic constituent layers are derived according to Trefftz’s formulation for elastic bodies under initial stress. The plate theory thus derived includes the microdeformation which can account for the heterogeneity of the plate. Flexural wave propagation under initial stress and buckling of a simply supported rectangular composite plate are investigated. In a special case of harmonic wave propagation in a free composite plate dispersion curves predicted by the plate equations are compared with the exact curve. Good agreement is observed for the complete plate theory and Approximation I, while the adequacy of the other two sets of simplified equations, Approximations II and III, depends vitally on the ratio of the transverse shear rigidities of the constituent materials.
