Abstract


The dynamic mechanical properties of finite two-dimensional periodic cellular materials are investigated by finite element eigenmode analysis for different architectures of the unit cell. Frequency band gaps are examined in quadratic and hexagonal lattice topologies with regular, inverted, and chiral architecture. Pronounced band gaps develop for chiral lattices. The formation of band gaps can be traced back to the resonance behavior of the elementary building blocks of the cellular structure for different boundary conditions (mode transition). Based on the findings of this work periodic lattice materials with specific band gaps can be designed. We show that periodic cellular materials with specific band gaps can be designed by means of FEM eigenmode analysis. The gap width and gap position strongly dependent on the geometry of the basic-cell. Our results reveal that the first band gap is associated with collective periodic rotation motions, and confirm that the band gap behavior is governed by the properties of the single strut. © 2013 WILEY-VCH Verlag GmbH & Co.
