  • Abstract
Based on the structure-preserving characteristics of the symplectic algorithm, the wave propagation problem of auxetic cellular structures is analyzed and compared with conventional cellular materials. The dispersion relations along the first Brillouin zone boundary and the contour plots of phase constant surfaces are obtained using the finite element method. Numerical results reveal the superiority of auxetic re-entrant honeycombs in sound reduction applications compared with conventional hexagon lattices. Band structures of the chiral honeycomb are developed to illustrate the unique feature of the symplectic algorithm at higher frequencies calculation. The highly-directional wave propagation properties of auxetic cellular structures are also analyzed, which will provide invaluable guidelines for the future application of auxetic cellular structures in sound insulation.
