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…
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…
