"The free propagation of elastic waves through periodic microstructured materials\r\ncan be studied by the analytical formulation of beam lattice models for the elementary cell, in\r\ncombination with the Floquet-Bloch theory. Within this framework, the present paper deals\r\nwith periodic tetrachiral materials characterized by a monoatomic cell. Alternative analytical\r\nformulations can be developed by continualization-homogenization techniques in micropolar\r\nequivalent continua, characterized by overall elastic and inertial tensors. Valid approaches\r\nfor the solution of the wave propagation problems are offered by perturbation methods, numerical\r\ncontinuation techniques, and – finally – computational analyses, suited to account for\r\nsome mechanical updates or improvements that can hardly be included in synthetic formulations.\r\nBased on these considerations, the dispersion curves achievable by different formulations\r\nare compared and discussed. The major interest is focused on the spectral effects\r\ndetermined by changes in the geometry, inertia, elasticity of the microstructural elements and,\r\nfinally, by variations in the cellular symmetry. Some attention is paid to the parameter combinations,\r\nwhich might open band gaps in the low-frequency range, useful to filter undesired\r\ndynamic signals for vibration shielding purposes."^^ .
