Hierarchical physically based machine learning in material science: the case study of spider silk
Vincenzo Fazio, Nicola Maria Pugno, Orazio Giustolisi +1
Multiscale phenomena exhibit complex structure-function relationships, and predicting their macroscopic behavior requires deducing differential equations at different scales. The c…
A new concept for superior energy dissipation in hierarchical materials and structures
G. Puglisi, N. M. Pugno
We propose a new conceptual approach to reach unattained dissipative properties based on the friction of slender concentric sliding columns. We begin by searching for the optimal t…
"Water to the ropes": a predictive model for the supercontraction stress of spider silks
Vincenzo Fazio, Nicola Maria Pugno, Giuseppe Puglisi
When humidified at different moisture conditions, restrained spider silk fibers can exhibit a very high supercontraction phenomenon. The hydration water molecules induce a Hydrogen…
Catastrophic thinning of dielectric elastomers
Giuseppe Zurlo, Michel Destrade, Domenico DeTommasi +1
We provide a clear energetic insight into the catastrophic nature of the so-called creasing and pull-in instabilities in soft electro-active elastomers. These phenomena are ubiquit…
Multiscale mechanics of macromolecular materials with unfolding domains
Domenico De Tommasi, Giuseppe Puglisi, Giuseppe Saccomandi
We propose a general multiscale approach for the mechanical behavior of three-dimensional networks of macromolecules undergoing strain-induced unfolding. Starting from a (statistic…
Failure mechanisms in thin electroactive polymer actuators
D. De Tommasi, G. Puglisi, G. Saccomandi +1
We propose a model to analyze the insurgence of pull-in and wrinkling failures in electroactive thin films. We take in consideration both cases of voltage and charge control, and s…
