We experimentally and numerically investigate elastic wave propagation in a class of
lightweight architected materials composed of hollow spheres and binders. Elastic wave …

This paper presents a general multiscale framework towards the computation of the
emergent effective elastodynamics of heterogeneous materials, to be applied for the …

In this paper, we establish well-posed boundary and interface conditions for the relaxed
micromorphic model that are able to unveil the scattering response of fully finite-size …

The effective dynamic properties of specific periodic structures involving rubber-like
materials can be adjusted by pre-strain, thus facilitating the design of custom acoustic filters …

In this manuscript, a reduced order homogenization model is developed for polycrystalline
microstructures with microstructurally small cracks. The proposed approach employs and …

When considering an effective, ie homogenized description of waves in periodic media that
transcends the usual quasi-static approximation, there are generally two schools of …

Metamaterials are artificial structures that can manipulate and control sound waves in ways
not possible with conventional materials. While much effort has been undertaken to widen …

The propagation of a wave pulse due to low-speed impact on a one-dimensional,
heterogeneous bar is studied. Due to the dispersive character of the medium, the pulse …

We present an inertia-augmented relaxed micromorphic model that enriches the relaxed
micromorphic model previously introduced by the authors via a term Curl P· in the kinetic …

While the design of always new metamaterials with exotic static and dynamic properties is
attracting deep attention in the last decades, little effort is made to explore their interactions …
