Selective mode conversion and rainbow trapping via graded elastic waveguides
Jacopo M. De Ponti, Luca Iorio, Emanuele Riva +3
We experimentally achieve wave mode conversion and rainbow trapping in an elastic waveguide loaded with an array of resonators. Rainbow trapping is a phenomenon that induces wave c…
Online structural health monitoring by model order reduction and deep learning algorithms
Luca Rosafalco, Matteo Torzoni, Andrea Manzoni +2
Within a structural health monitoring (SHM) framework, we propose a simulation-based classification strategy to move towards online damage localization. The procedure combines para…
Experimental investigation of amplification, via a mechanical delay-line, in a rainbow-based metasurface for energy harvesting
Jacopo M. De Ponti, Andrea Colombi, Emanuele Riva +4
We demonstrate that a rainbow-based metasurface, created by a graded array of resonant rods attached to an elastic beam, operates as a mechanical delay-line by slowing down surface…
Fully convolutional networks for structural health monitoring through multivariate time series classification
Luca Rosafalco, Andrea Manzoni, Stefano Mariani +1
We propose a novel approach to Structural Health Monitoring (SHM), aiming at the automatic identification of damage-sensitive features from data acquired through pervasive sensor s…
Graded metasurface for enhanced sensing and energy harvesting
Jacopo M. De Ponti, Andrea Colombi, Raffaele Ardito +3
In elastic wave systems, combining the powerful concepts of resonance and spatial grading within structured surface arrays enable resonant metasurfaces to exhibit broadband wave fo…
