The speed of a solitary wave in a chain of beads is a function of its amplitude, and the details of the beads' contact force. By varying the amplitude of the incoming pulse, and measuring the time-of-flight (ToF), the effect that an added fluid has on the contact force was investigated. It was found that the fluid's rheological properties have non trivial effects on the ToF. This suggests that the ToF of the solitary wave could be a good measurable magnitude characterizing some of the…

Solitary waves in a chain of beads under Hertz contact

We study experimentally the propagation of high-amplitude compressional waves in a chain of beads in contact, submitted or not to a small static force. In such a system, solitary waves have been

Strongly nonlinear waves in a chain of Teflon beads.

One-dimensional "sonic vacuum" type phononic crystals were assembled from a chain of polytetrafluoroethylene (PTFE,Teflon) spheres with different diameters in a Teflon holder and demonstrated that it supports propagation of strongly nonlinear solitary waves with a very low speed.

Propagation of nonlinear compression pulses in granular media

The study of mechanics of a granular medium is of substantial interest, both scientifically and for the solution of applied problems. Such materials are, for example, good buffers for shock loads.

On the validity of Hertz contact law for granular material acoustics

Abstract:We discuss the acoustical behavior of a 1D model of granular medium, which is a chain of identical spherical beads. In this geometry, we are able to test quantitatively alternative models to

Influence of Controlled Viscous Dissipation on the Propagation of Strongly Nonlinear Waves in Stainless Steel Based Phononic Crystals

Strongly nonlinear phononic crystals were assembled from stainless steel spheres. Single solitary waves and splitting of an initial pulse into a train of solitary waves were investigated in different

Dissipative solitary waves in granular crystals.

A quantitatively accurate extension of the Hertzian model is proposed that encompasses dissipative effects via a discrete Laplacian of the velocities in one-dimensional granular crystals.

How does the ball-chain work?

A well‐known collision experiment can be carried out with an arrangement of several elastic balls suspended in a horizontal row. As we have shown in a previous article a necessary condition for the

Interaction of highly nonlinear solitary waves with linear elastic media.

This preliminary study establishes the foundation for utilizing reflected solitary waves as novel information carriers in nondestructive evaluation of elastic material systems.

Low-frequency behavior of beads constrained on a lattice.

An interpretation of the non-Hertzian behavior of sound propagation in a triangular lattice of spherical beads under isotropic stress in terms of progressive activation of contacts, in discrepancy with previous models involving buckling of force chains.
