Elasto-Dynamic Behavior Of A 2D Square Lattice With Entrained Fluid

11Th World Congress On Computational Mechanics; 5Th European Conference On Computational Mechanics; 6Th European Conference On Computational Fluid Dynamics, Vols Ii - Iv
Numerical investigation of wave propagation in a cellular solid with closed cells configuration and entrained fluid showed an existence of two types of pressure waves, which have opposite polarization and have different phase and group velocities. This is in agreement with the Biot's theory, unless that the slow pressure wave appears beyond the first resonant frequency of the skeleton members. In order to explain this fact we propose an analytical machro-mechanical model and study dynamical modes contribution.
