Anisotropic frictional model for an object sliding in a granular media
René Zuñiga, Carlos Vasconcellos, Baptiste Darbois Texier +1
Several locomotion strategies are based on the anisotropic nature of the forces experienced by the moving body with its environment. We report experiments on the anisotropy of the…
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 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…
Mechanical impulse propagation in a packing of 3D spheres confined at constant pressure
Francisco Santibanez, Rene Zuñiga, Francisco Melo
Mechanical impulse propagation in granular media depends strongly on the imposed confinement conditions. In this work, the propagation of sound in a granular packing contained by f…
