Predictive beam-lattice reduction for higher-order topological modes in a 2D SSH phononic crystal
Eloi Perez Compte, Michele Brun, Giorgio Carta +3
We develop a mechanically faithful reduced model for a two-dimensional topological phononic crystal composed of rigid square masses connected by slender elastic ligaments. Exploiti…
Longitudinal-flexural wave mode conversion via periodically undulated waveguides with constant and graded profiles
Vinicius F. Dal Poggetto, Fabio Nistri, Nicola M. Pugno +3
Wave mode conversion allows to transform energy from one propagating wave type to another at a boundary where a change in material properties or geometry occurs. Converting longitu…
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…
A frequency-preserving and time-invariant metamaterial-based nonlinear acoustic diode
Antonio S. Gliozzi, Marco Miniaci, Anastasiia O. Krushynska +4
We present the realization of an acoustic diode or rectifier, exploiting symmetry-breaking nonlinear effects like harmonic generation and wave mixing and the filtering capabilities…
Proof of concept for an ultrasensitive meta-device to detect and localize nonlinear elastic sources
Marco Miniaci, Antonio S. Gliozzi, Bruno Morvan +4
The appearance of nonlinear effects in elastic wave propagation is one of the most reliable and sensitive indicators of the onset of material damage. However, these effects are usu…
