Following a brief review of current progress in the field of nonlinear targeted energy transfer
(TET), we discuss some general ideas and methods in this field and describe certain …

Phononic materials are periodically arranged building blocks in the form of material
properties, geometries, and/or boundary conditions. This synthetic architecture makes …

Nonlinearity in dynamics and acoustics may be viewed as scattering of energy across
frequencies/wavenumbers. This is in contrast with linear systems when no such scattering …

Granular media composed of ordered arrays of discrete spherical granules have attracted
considerable attention due to their highly nonlinear and discontinuous dynamics and …

We study the highly complex wave transmission at the interface between a two-dimensional
(2D) hexagonally structured granular medium and a linearly elastic thin plate; we refer to this …

In this paper we investigate an elastically linked, nonlinear, in-plane rotator system and
experimentally study its nonreciprocal impulse response. The nonlinearity of the system …

Wave-wave interactions in a nonlinear metamaterial or structure with two propagating waves
can induce energy exchange within the nonlinear systems. The effects of nonlinear …

We study nonreciprocal wave transmission across the interface of two dissimilar granular
media separated by an elastic solid medium. Specifically, a left, larger-scale and a right …

In this work we study computationally nonlinear wave scattering at the flexible interfaces of
1D dimer granular chains with a square membrane with a linear uniform elastic foundation …

We consider the common problem setting of an elastic sphere impacting on a flexible beam.
In contrast to previous studies, we analyze the modal energy distribution induced by the …
