On the dynamic behavior of poroelastic materials

摘要: Poroelastic materials are two phase material systems consisting of a porous linear elastic solid filled with Newtonian viscous fluid. Analytical investigations have demonstrated that poroelastic structures can, depending on loading and geometry, exhibit response or the creep relaxation associated various models viscoelastic materials. This paper examines dynamic to harmonic disk slab material. Biot’s theory for deformable media is applied derive expressions complex modulus in terms coefficients. Both quasistatic analysis, accounting dissipation but neglecting inertia, which neglects dissipation, presented. For choice coefficients roughly appropriate water sandstone compact bone, layer shown rubber‐to‐glass transition low‐frequency range. Resonance effect...
