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…
Predicting the failure of two-dimensional silica glasses
Francesc Font-Clos, Marco Zanchi, Stefan Hiemer +4
Being able to predict the failure of materials based on structural information is a fundamental issue with enormous practical and industrial relevance for the monitoring of devices…
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…
Universal low-frequency vibrational modes in silica glasses
Silvia Bonfanti, Roberto Guerra, Chandana Mondal +2
It was recently shown that different simple models of glass formers with binary interactions define a universality class in terms of the density of states of their quasi-localized…
Unjamming of active rotators
Linda Ravazzano, Maria Chiara Lionetti, Maria Rita Fumagalli +5
Active particle assemblies can exhibit a wide range of interesting dynamical phases depending on internal parameters such as density, adhesion strength or self-propulsion. Active s…
Automatic Design of Mechanical Metamaterial Actuators
Silvia Bonfanti, Roberto Guerra, Francesc Font Clos +2
Mechanical metamaterials actuators achieve pre-determined input--output operations exploiting architectural features encoded within a single 3D printed element, thus removing the n…
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…
Oscillatory Instabilities in 3-Dimensional Frictional Granular Matter
Silvia Bonfanti, Joyjit Chattoraj, Roberto Guerra +2
The dynamics of amorphous granular matter with frictional interactions cannot be derived in general from a Hamiltonian and therefore displays oscillatory instabilities stemming fro…
