Summary:
Excitation, propagation, and interaction of nonlinear localized oscillations in a mass-spring chain are studied. Letting the mass at one end of the chain driven sinusoidally at high frequency and large amplitude, localized oscillations can be excited intermittently near the end and propagated down the chain one after another at a constant speed. We have experimentally observed the phenomena, supratransmission, by a mechanical mass-spring chain which emulates the Fermi-Pasta-Ulam one of beta type.
