The strange case of Negative Reflection
Bibinur Meirbekova, Lorenzo Morini, Michele Brun +1
In this paper we show for the first time the phenomenon of negative reflection in a simple mechanical structure. The latter is a grating of fixed inclusions embedded in a linear el…
Hierarchical auxetic and isotropic porous medium with extremely negative Poisson's ratio
Maryam Morvaridi, Giorgio Carta, Federico Bosia +4
We propose a novel two-dimensional hierarchical auxetic structure consisting of a porous medium in which a homogeneous matrix includes a rank-two set of cuts characterised by diffe…
Transformation design of in-plane elastic cylindrical cloaks, concentrators and lenses
Michele Brun, Sebastien Guenneau
We analyse the elastic properties of a class of cylindrical cloaks deduced from linear geometric transforms in the framework of the Milton-Briane- Willis clo…
Platonic crystal with low-frequency locally resonant snail structures. Wave trapping, transmission amplification and shielding
M. Morvaridi, G. Carta, M. Brun
We propose a new type of platonic crystal. The proposed microstructured plate includes snail resonators with low-frequency resonant vibrations. The particular dynamic effect of the…
A class of auxetic three-dimensional lattices
Luigi Cabras, Michele Brun
We propose a class of auxetic three-dimensional lattice structures. The elastic microstructure can be designed in order to have omni-directional Poisson's ratio arbitrarily close t…
Porous Materials with Omnidirectional Negative Poisson's Ratio
Giorgio Carta, Michele Brun, Antonio Baldi
This paper presents an auxetic medium, consisting of a two-dimensional perforated sheet where the holes are arranged in a repetitive pattern. The hexagonal disposition of the perfo…
