We study the complex nonlinear mechanism of uni- and bi-directional energy channeling realized in a locally resonant three-dimensional (3D) unit-cell model comprising of an external mass subjected to a 3D nonlinear local ...

The current study dwells on the wave propagation in one-dimensional periodic granular dimer (diatomic) chain mounted on linear elastic foundation. We invoke multiple time scales and partition the dynamics of the perturbed ...
