Chaos and Anderson-like localization in polydisperse granular chains
Chaos and Anderson-like localization in polydisperse granular chains
We investigate the dynamics of highly polydisperse finite granular chains. From the spatiospectral properties of small vibrations, we identify which particular single-particle displacements lead to energy localization. Then, we address a fundamental question: Do granular nonlinearities and the resulting chaotic dynamics destroy this energy localization? Our numerical simulations show that …
