Topological bands and localized vibration modes in quasiperiodic beams
Raj Kumar Pal, Matheus I. N. Rosa, Massimo Ruzzene
We investigate a family of quasiperiodic continuous elastic beams, the topological properties of their vibrational spectra, and their relation to the existence of localized modes.…
Edge states and topological pumping in elastic lattices with periodically modulated coupling
Matheus I. N. Rosa, Raj Kumar Pal, José R. F. Arruda +1
We investigate the dispersion topology of elastic lattices characterized by spatial stiffness modulation. The modulation is defined by the sampling of a two-dimensional surface, wh…
Valley based splitting of topologically protected helical waves in elastic plates
Marco Miniaci, Raj Kumar Pal, Raffaele Manna +1
Topological protection offers unprecedented opportunities for wave manipulation and energy transport in various fields of physics, including elasticity, acoustics, quantum mechanic…
Tunable wave propagation by varying prestrain in tensegrity-based periodic media
Raj Kumar Pal, Massimo Ruzzene, Julian J. Rimoli
This paper investigates the dynamic properties of one, two and three-dimensional tensegrity-based periodic structures introduced in Rimoli and Pal, Comp. B, 2017, which are here te…
Observation of topological valley modes in an elastic hexagonal lattice
Javier Vila, Raj K. Pal, Massimo Ruzzene
We report on the experimental observation of topologically protected edge waves in a two-dimensional elastic hexagonal lattice. The lattice is designed to feature K point Dirac con…
