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…
A study of deformation localization in nonlinear elastic lattices
Raj Kumar Pal, Federico Bonetto, Luca Dieci +1
The paper investigates localized deformation patterns resulting from the onset of instabilities in lattice structures. The study is motivated by previous observations on discrete h…
