Amplitude-dependent edge states and discrete breathers in nonlinear modulated phononic lattices
Matheus I. N. Rosa, Michael J. Leamy, Massimo Ruzzene
We investigate the spectral properties of one-dimensional spatially modulated nonlinear phononic lattices, and their evolution as a function of amplitude. In the linear regime, the…
Topological Invariant and Anomalous Edge Modes of Strongly Nonlinear Systems
Di Zhou, D. Zeb Rocklin, Michael Leamy +1
Despite the extensive studies of topological states, their characterization in strongly nonlinear classical systems has been lacking. In this work, we identify the proper definitio…
Experimental Realization of a Reconfigurable Electroacoustic Topological Insulator
Amir Darabi, Manuel Collet, Michael J Leamy
A substantial challenge in guiding elastic waves is the presence of reflection and scattering at sharp edges, defects, and disorders. Recently, mechanical topological insulators ha…
Application of the method of multiple scales to unravel energy exchange in nonlinear locally resonant metamaterials
P. B. Silva, M. J. Leamy, M. G. D. Geers +1
In this paper, the effect of weak nonlinearities in 1D locally resonant metamaterials is investigated via the method of multiple scales. Commonly employed to the investigate the ef…
Amplitude-dependent topological edge states in nonlinear phononic lattices
Raj Kumar Pal, Javier Vila, Michael Leamy +1
This work investigates the effect of nonlinearities on topologically protected edge states in one and two-dimensional phononic lattices. We first show that localized modes arise at…
