Dispersive wave propagation in two-dimensional rigid periodic blocky materials with elastic interfaces
Andrea Bacigalupo, Luigi Gambarotta
Dispersive waves in two-dimensional blocky materials with periodic microstructure made up of equal rigid units having polygonal centro-symmetric shape with mass and gyroscopic iner…
Wave propagation in non-centrosymmetric beam-lattices with lumped masses: discrete and micropolar modelling
Andrea Bacigalupo, Luigi Gambarotta
The in-plane acoustic behavior of non-centrosymmetric lattices having nodes endowed with mass and gyroscopic inertia and connected by massless ligaments with asymmetric elastic pro…
Optimal design of low-frequency band gaps in anti-tetrachiral lattice meta-materials
Andrea Bacigalupo, Giorgio Gnecco, Marco Lepidi +1
The elastic wave propagation is investigated in the beam lattice material characterized by a square periodic cell with anti-tetrachiral microstructure. With reference to the Floque…
Design of acoustic metamaterials through nonlinear programming
Andrea Bacigalupo, Giorgio Gnecco, Marco Lepidi +1
The dispersive wave propagation in a periodic metamaterial with tetrachiral topology and inertial local resonators is investigated. The Floquet-Bloch spectrum of the metamaterial i…
Optimal design of auxetic hexachiral metamaterials with local resonators
Andrea Bacigalupo, Marco Lepidi, Giorgio Gnecco +1
A parametric beam lattice model is formulated to analyse the propagation properties of elastic in-plane waves in an auxetic material based on a hexachiral topology of the periodic…
Simplified modelling of chiral lattice materials with local resonators
Andrea Bacigalupo, Luigi Gambarotta
A simplified model of periodic chiral beam-lattices containing local resonators has been formulated to obtain a better understanding of the influence of the chirality and of the dy…
Homogenization of periodic hexa- and tetrachiral cellular solids
Andrea Bacigalupo, Luigi Gambarotta
The homogenization of auxetic cellular solids having periodic hexachiral and tetrachiral microstructure is dealt with two different techniques. The first approach is based on the r…
