Fracture toughness and auxeticity in disordered metamaterials
Hannes Holey, Andrea Lorenzo Henri Sergio Detry, Silvia Bonfanti +6
Auxetic metamaterials are commonly thought to exhibit favorable mechanical properties, notably high energy absorption. Here we investigate disordered metamaterials obtained from ra…
Quasi-localized modes in crystalline high entropy alloys
Silvia Bonfanti, Roberto Guerra, Rene Alvarez-Donado +3
High Entropy Alloys (HEAs) are designed by mixing multiple metallic species in nearly the same amount to obtain crystalline or amorphous materials with exceptional mechanical prope…
Universal Density of Low Frequency States in Silica Glass at Finite Temperatures
Roberto Guerra, Silvia Bonfanti, Itamar Procaccia +1
The theoretical understanding of the low-frequency modes in amorphous solids at finite temperature is still incomplete. The study of the relevant modes is obscured by the dressing…
Elementary plastic events in amorphous silica
Silvia Bonfanti, Roberto Guerra, Chandana Mondal +2
Plastic instabilities in amorphous materials are often studied using idealized models of binary mixtures that do not capture accurately molecular interactions and bonding present i…
