Descrizione del progetto
Una nuova classe di metamateriali meccanici bioispirati
Lo sviluppo tecnologico di una nuova classe di metamateriali meccanici bioispirati (materiali progettati artificialmente con proprietà vibrazionali extra-esotiche non presenti in natura) è l’obiettivo del progetto BOHEME, finanziato dall’UE. Sulla base di una ricerca in varie discipline (da biologia e matematica a ingegneria oceanica e scienza dei materiali), si ritiene che il principio di funzionamento dietro ai metamateriali sia già sfruttato in natura e che, attraverso l’evoluzione, abbia condotto a progettazioni ottimizzate per lo smorzamento dell’impatto. BOHEME si servirà di un approccio rivoluzionario per applicazioni su diverse scale di lunghezza, da prove non distruttive a riduzione del rumore, controllo delle vibrazioni a bassa frequenza (tra cui i sismi) e tutela delle coste o raccolta di energia dalle onde oceaniche.
Obiettivo
BOHEME’s ambitious goal is to design and realize a new class of bioinspired mechanical metamaterials for novel applicative tools in diverse technological fields. Metamaterials exhibit exotic vibrational properties currently unavailable in Nature, and numerous important applications are emerging. However, universally valid design criteria are currently lacking, and their effectiveness is presently restricted to limited frequency ranges.
BOHEME starts from an innovative assumption, increasingly supported by experimental evidence, that the working principle behind metamaterials is already exploited in Nature, and that through evolution, this has given rise to optimized designs for impact damping. The “fundamental science” part of the project aims to explore biological structural materials for evidence of this, to investigate novel optimized bioinspired designs (e.g. porous hierarchical structures spanning various length scales) using state-of-the-art analytical and numerical approaches, to design and manufacture vibrationally effective structures, and to experimentally verify their performance over wide frequency ranges.
Through this disruptive approach, BOHEME will provide a pipeline to the technological development of a new class of bioinspired metamaterials in innovative applicative sectors over various wavelength scales, from non-destructive testing, to noise reduction, to low-frequency vibration control (including seismic), to coastal protection or energy harvesting from ocean waves. Industrial partners will provide know-how for proof of principle experiments and possible prototypes. The project is ambitious and inherently multidisciplinary, involving research in biology, mathematics, physics, materials science, structural and ocean engineering, drawing from scientific excellence of the partners. It involves theoretical, numerical and experimental aspects, and is a high-impact endeavour, from which basic science, EU industry and society can benefit.
