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…
Silicon cantilevers locally heated from 300K up to the melting point: temperature profile measurement from their resonances frequency shift
Basile Pottier, Felipe Aguilar, Mickaël Geitner +2
When heated, micro-resonators present a shift of their resonance frequencies. We study specifically silicon cantilevers heated locally by laser absorption, and evaluate theoretical…
Progressive friction mobilization and enhanced Janssen's screening in confined granular rafts
Oscar V. Saavedra, Hervé Elettro, Francisco Melo
Confined two-dimensional assemblies of floating particles, known as granular rafts, are prone to develop a highly nonlinear response under compression. Here we investigate the tran…
Helical locomotion in granular media
Baptiste Darbois Texier, Alejandro Ibarra, Francisco Melo
The physical mechanisms that bring about the propulsion of a rotating helix in a granular medium are considered. A propulsive motion along the axis of the rotating helix is induced…
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…
High Resolution Viscosity Measurement by Thermal Noise Detection
Felipe Aguilar Sandoval, Manuel Sepúlveda, Ludovic Bellon +1
An interferometric method is implemented in order to accurately assess the thermal fluctuations of a micro-cantilever sensor in liquid environments. The power spectrum density (PSD…
