Material vs. structure: Topological origins of band-gap truncation resonances in periodic structures
Matheus I. N. Rosa, Bruce L. Davis, Liao Liu +2
While resonant modes do not exist within band gaps in infinite periodic materials, they may appear as in-gap localized edge modes once the material is truncated to form a finite pe…
The role of nonlinearities in topological protection: using magnetically coupled fidget spinners
Javier Vila, Glaucio H. Paulino, Massimo Ruzzene
We investigate and experimentally observe the existence of topologically protected interface modes in a one-dimensional mechanical lattice, and we report on the effect of nonlinear…
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…
Wave Propagation in Undulated Structural Lattices
Giuseppe Trainiti, Julian J. Rimoli, Massimo Ruzzene
This work investigates wave propagation in undulated square structural lattices. The undulated pattern is obtained by imposing an initial curvature to the lattice's elements. The s…
A discrete model and analysis of one dimensional deformations in a structural interface with micro-rotations
Aleksey A. Vasiliev, Andrey E. Miroshnichenko, Massimo Ruzzene
The static and dynamic properties of a Cosserat-type lattice interface of finite thickness are studied, so that both displacements and rotational degrees of freedom are taken into…
