主 题:Biot's theory poroelasticity cellular solids band structure fluid-structure interaction
摘 要:In the present paper, the performance of Biot s theory is investigated for wave propagation in cellular and porous solids with entrained fluid for configurations with well-known drained (no fluid) mechanical properties. Cellular solids differ from porous solids based on their relative density rho* 1. For frequencies below the first resonance of the lattice walls, only the fast-pressure mode of the two modes predicted by Biot s theory is found. It is also shown that homogenized models for shear waves based on microstructural deformations for drained conditions agree with Biot s theory.
