Dynamics and topology of non-Hermitian elastic lattices with non-local feedback control interactions
Matheus I. N. Rosa, Massimo Ruzzene
We investigate non-Hermitian elastic lattices characterized by non-local feedback control interactions. In one-dimensional lattices, we show that the proportional control interacti…
Edge States and Topological Pumping in Stiffness Modulated Elastic Plates
Emanuele Riva, Matheus I. N. Rosa, Massimo Ruzzene
We demonstrate that modulations of the stiffness properties of an elastic plate along a spatial dimension induce edge states spanning non-trivial gaps characterized by integer valu…
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…
