Scattering of solitary waves in granular media

TL;DR

This paper presents a numerical analysis of how solitary waves scatter in granular media with Hertzian contact, revealing secondary multipulse structures at interfaces similar to those previously observed by Nesterenko and colleagues.

Contribution

It uncovers the formation of secondary multipulse structures during solitary wave scattering in granular media, extending prior findings to new interface conditions.

Findings

Secondary multipulse structures are generated at the interface.

Structures resemble those previously identified by Nesterenko.

Results enhance understanding of wave behavior in granular media.

Abstract

A detailed numerical study of the scattering of solitary waves by a barrier, in a granular media with Hertzian contact, shows the existence of secondary multipulse structures generated at the interface of two "sonic vacua", which have a similar structure as the one previously found by Nesterenko and coworkers.
