“…Although very effective, such techniques may require intensive computations and may lead to complex geometries difficult to manufacture and whose performance may lack in robustness. The application of periodic structural networks as phononic materials may potentially lead to a simplified design process, where a limited number of continuously varying parameters defines the geometry of a predefined cellular topology [9]. The successful application of this approach clearly requires identifying lattice configurations that provide sufficient design flexibility, as well as with strongly dependent elasto-dynamic properties upon a limited number of geometric parameters defining the lattice configuration.…”

a b s t r a c tThe manuscript reports the outcome of investigations on the phononic properties of a chiral cellular structure. The considered geometry features in-plane hexagonal symmetry, whereby circular nodes are connected through six ligaments tangent to the nodes themselves. In-plane wave propagation is analyzed through the application of Bloch theorem, which is employed to predict two-dimensional dispersion relations as well as illustrate dispersion properties unique to the considered chiral configuration. Attention is devoted to determining the influence of unit cell geometry on dispersion, band gap occurrence and wave directionality. Results suggest cellular lattices as potential building blocks for the design of meta-materials of interest for acoustic wave-guiding applications.

“…Additional simplification is possible in the case of symmetry within the unit cell itself. Exploiting this symmetry, the first Brillouin zone can be further reduced to an irreducible Brillouin zone which is the smallest zone in the wave domain that contains all information [6,14].…”

With the fast development of computational mechanics and the capacity as well as the speed of modern computers, simulation-based structural optimization has become an indispensable tool in the design process of competitive products. This paper presents a brief description of the current status of structural optimization by reviewing some significant progress made in the last decades. Potential research topics are also discussed. The entire literatures of the field are not covered due to the limitation of the length of paper. The scope of this review is limited and closely related to the authors' own research interests.
