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…
