Tunable topological edge modes in Su-Schrieffer-Heeger arrays
G. J. Chaplain, A. S. Gliozzi, B. Davies +4
A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtai…
Tunable topologically protected waveguiding in auxetic nonlinear metamaterials
M. Morvaridi, F. Bosia, M. Brun +6
In this paper, we discuss the possibility of achieving tunable topologically protected edge modes through the application of uniaxial deformation in an auxetic metamaterial. The pr…
Source and defect localization in thin elastic plates of arbitrary geometry using eigenmodes
Martin Lott, Antonio S. Gliozzi, Federico Bosia
In this paper, we experimentally demonstrate how discrete resonances can be used to image acoustic sources and mechanical changes in thin plates with different boundary shapes. The…
Robust substrate anchorages of silk lines with extensible nano-fibres
Jonas O. Wolff, Daniele Liprandi, Federico Bosia +2
Living systems are built of multiscale-composites: materials formed of components with different properties that are assembled in complex micro- and nano-structures. Such biologica…
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…
Band gap enhancement in periodic frames using hierarchical structures
Vinícius F. Dal Poggetto, Federico Bosia, Marco Miniaci +1
The quest for novel designs for lightweight phononic crystals and elastic metamaterials with wide lowfrequency band gaps has proven to be a significant challenge in recent years. I…
Correlation between slip precursors and topological length scales at the onset of frictional sliding
Gianluca Costagliola, Federico Bosia, Nicola M. Pugno
Understanding the interplay between concurrent length scales is a fundamental issue in many problems involving friction between sliding interfaces, from tribology to the study of e…
Design and characterization of cochlea-inspired tonotopic resonators
Vinicius F. Dal Poggetto, Federico Bosia, David Urban +3
The cochlea has long been the subject of investigation in various research fields due to its intriguing spiral architecture and unique sensing characteristics. One of its most inte…
Toughening and mechanosensing in bone: a perfectly balanced mechanism based on competing stresses
M. Fraldi, A. Cutolo, A. R. Carotenuto +3
Bone is a stiff and though, hierarchical and continuously evolving material that optimizes its structure to respond to mechanical stimuli, which also govern growth and remodeling p…
Topologically engineered 3D printed architectures with superior mechanical strength
R. S. Ambekar, B. Kushwaha, P. Sharma +4
Materials that are lightweight yet exhibit superior mechanical properties are of compelling importance for several technological applications that range from aircrafts to household…
A combined experimental/numerical study on the scaling of impact strength and toughness in composite laminates for ballistic applications
Stefano Signetti, Federico Bosia, Seunghwa Ryu +1
In this paper, the impact behaviour of composite laminates is investigated, and their potential for ballistic protection assessed, as a function of the reinforcing materials and st…
Unveiling a new shear stress transfer mechanism in composites with helically wound hierarchical fibres
A. Cutolo, A. R. Carotenuto, S. Palumbo +3
The mechanical performance of reinforced composites is strongly influenced at different scales by the stress transferred at the matrix-fibre interfaces and at any surface where mat…
