Geometry-controlled phase transition in vibrated granular media
René Zuñiga, Germán Varas, Stéphane Job
We report experiments on the dynamics of vibrated particles constrained in a two-dimensional vertical container, motivated by the following question: how to get the most out of a g…
Localized energy absorbers in Hertzian chains
Carlos Vasconcellos, René Zuñiga, Stéphane Job +1
Energy absorbers and energy-harvesting devices have been under the scope of scientists and engineers for decades to fulfill specific technological needs, mainly concerned with soun…
Effect of lateral confinement on the apparent mass of particle dampers
María Victoria Ferreyra, Mauro Baldini, Luis A. Pugnaloni +1
We study, via DEM simulations, the apparent mass and loss factor of particle dampers (PD) attached to a vertically driven, single degree of freedom mechanical system. Altho…
Effect of an interstitial fluid on the dynamics of three-dimensional granular media
Rene Zuniga, Stephane Job, Francisco Santibanez
The propagation of mechanical energy in granular materials has been intensively studied in recent years given the wide range of fields that have processes related to this phenomena…
Experimental evidence of solitary wave interaction in Hertzian chains
F. Santibanez, R. Munoz, A. Caussarieu +2
We study experimentally the interaction between two solitary waves that approach one to another in a linear chain of spheres interacting via the Hertz potential. When these counter…
Intrinsic Energy Localization through Discrete Gap Breathers in One-Dimensional Diatomic Granular Crystals
G. Theocharis, N. Boechler, P. G. Kevrekidis +3
We present a systematic study of the existence and stability of discrete breathers that are spatially localized in the bulk of a one-dimensional chain of compressed elastic beads t…
