Energy flow, connectivity and entropy in the light of fuzzy structures
Antonio Carcaterra, Adnan Akay · The Journal of the Acoustical Society of America · 2021
Fuzzy structures, as presented in the literature, refer to a dynamic coupling between a master and a population of slave resonators of uncertain characteristics. However, the investigation of such systems opened new perspectives looking at the way energy flows between the two components, the masters and the slaves. New elements, not originally included into the concept of fuzzy, have been subject of investigations (Carcaterra-Akay, JASA, JSV) disclosing relevant questions: how the topology of connectivity between master and slaves affects the energy transfer? Can be a thermodynamic analogy established between fuzzy structures and thermal systems? Can entropy gain a role in structural dynamics, as it plays a key role in thermodynamics? This paper makes a historical reconstruction of these puzzling questions related to fuzzy structures.
