A Combined Microbeam and Phase-Field Approach to Identify the Toughness and Ultimate Strength of Amorphous Silica
Gustavo Alberto Rosales-Sosa, Gergely Molnar, Yoshinari Kato +7
This work presents a new approach to evaluating the toughness, described by the critical energy release rate (), and ultimate tensile strength () of amorphous silica (SiO…

How glass breaks -- Damage explains the difference between surface and fracture energies in amorphous silica
Gergely Molnár, Etienne Barthel
The difference between free surface energy and fracture toughness in amorphous silica is studied via multi-scale simulations. We combine the homogenization of a molecular dynamics…

Thermomechanical Dissipative behaviour of CuZr metallic glasses
Matias Sepulveda-Macias, Gergely Molnár, Anne Tanguy
We performed molecular dynamics simulations of ZrCu metallic glass samples submitted to mechanical deformation at different strain rates. The simultaneous measurement…
