Metamaterials, man-made composites that are scaled smaller than the wavelength, have
demonstrated a huge potential for application in acoustics, allowing the production of sub …

Multi-scale models enriched with the second gradient of the displacement field and based
on the concept of representative volume element (RVE) are examined and discussed in …

The study of material failure phenomena with coupled multiple scales is a need and a
challenge. The fundamental difficulty in these problems is due to multiscale bridging …

As a passive technology for vibration reduction, embedded acoustic black holes (EABHs)
have been extensively studied in the last decades. Due to the substantial decrease of …

In this contribution, we propose a novel continuum mechanical concept to determine the
homogenised mechanical response of random fibre networks. Their free energy is …

This paper presents a numerical multiscale formulation for analysis of the transient heat and
fluid flow in deformable heterogeneous porous media. Due to the heterogeneity of the …

Broadband sound attenuation at low frequency ranges (below 500 Hz) has been a
challenge in the acoustics field which cannot be solved, via conventional materials, unless …

In this paper, a computational homogenization technique is developed for fluid flow through
the deformable micro-fractured porous media. The coupled hydro-mechanical analysis is …

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 …

Abstract The so-called Locally Resonant Acoustic Metamaterials (LRAM) are considered for
the design of specifically engineered devices capable of stopping waves from propagating …
