Low-and high-frequency Stoneley waves, reflection and transmission at a Cauchy/relaxed micromorphic interface
Alexios Aivaliotis, Ali Daouadji, Gabriele Barbagallo +3
In this paper we study the reflective properties of a 2D interface separating a homogeneous solid from a band-gap metamaterial by modeling it as an interface between a classical Ca…
Relaxed micromorphic model of transient wave propagation in anisotropic band-gap metastructures
Gabriele Barbagallo, Domenico Tallarico, Marco Valerio D'Agostino +3
In this paper, we show that the transient waveforms arising from several localised pulses in a micro-structured material can be reproduced by a corresponding generalised continuum…
Relaxed micromorphic modeling of the interface between a homogeneous solid and a band-gap metamaterial: new perspectives towards meta-structural design
Angela Madeo, Gabriele Barbagallo, Manuel Collet +3
In the present paper, the material parameters of the isotropic relaxed micromorphic model derived for a specific metamaterial in a previous contribution are used to model its trans…
Bias extension test on an unbalanced woven composite reinforcement: Experiments and modeling via a second-gradient continuum approach
Gabriele Barbagallo, Angela Madeo, Ismael Azehaf +3
The classical continuum models used for the woven fabrics do not fully describe the whole set of phenomena that occur during the testing of those materials. This incompleteness is…
