Emergence of Pseudo-Phononic Gaps in Periodically Architected Pendulums
[article]

pre-print
Rejection of unmitigated vibrational disturbances represents an ongoing dilemma in complex linkage systems. In this work, we show evidence of an inherent and self-reliant vibration isolation mechanism in architected periodic chains of serially pivoted pendulums. Absorption of external excitations is achieved by virtue of Bragg-type band gaps which stem from the emergent chain dynamics. Owing to its coupled dynamics, the self-repeating cell of a Phononic Crystal (PC) is not trivial and cannot be
