Locally resonant metamaterials have attracted a lot of interest in recent years thanks to their capability to manipulate elastic waves. They typically consist of periodically distributed resonant elements, e.g. soft inclusions in a stiff matrix, that interact with the propagating wave, leading to the formation of band gaps, which can be interpreted as an interval of negative homogenized...

In recent years, metamaterials have received a great deal of research attention due to their potential for energy dissipation. Their ability to finely tune critical modes and to harness non-Eulerian instability mechanisms (such as snap-through) opens the way to substantial energy absorption while preserving elastic reversibility. Remarkably, these dynamic and dissipative characteristics are...

Homogenization of lattice metamaterials enables modelling lattice cells as equivalent solid structures with anisotropic mechanical properties. This aspect enables performing preliminary structural analysis of mechanical components made of metamaterials without modelling the entire lattice cells thus saving computational cost. Elastic homogenization has been widely explored in the literature...

Quasi-static homogenisation of two-dimensional periodic networks of elastic rods provides an effective approach to characterising the mechanical properties of the corresponding equivalent continua. In particular, the macroscopic response of the homogenised material can be tailored by tuning the geometrical and mechanical parameters of the underlying network [1,2].

Mechanical metamaterials with periodic mesostructures pose severe challenges for full-field measurement techniques when subjected to large deformations. In this contribution, we present a model-driven Digital Volume Correlation (DVC) strategy that tightly couples continuum modeling with experimental analyses of pantographic metamaterials tested within a tomographic chamber.
At the...

The intricate architectures of phononic crystals and metamaterials induce sophisticated wave behaviors that are directly tied to their internal geometries. While high-fidelity numerical models resolve these effects accurately, the computational overhead becomes prohibitive during extensive time-domain studies. To bridge this gap, effective continuum frameworks have emerged as a way to simulate...

We investigate the propagation of elastic waves with time-varying amplitudes in solids with "active" microstructure described by vector-valued phase fields. Depending on the constitutive choices adopted for the microstructural actions, the linearized evolution equations involve a non-normal matrix.
