Fracture initiation in silicate glasses via a universal shear localization mechanism

Matthieu Bourguignon, Gustavo Alberto Rosales-Sosa, Yoshinari Kato, Bruno Bresson et autres

Linking crack initiation in silicate glasses to shear banding identifies shear localization as a key driver of fracture in this archetypal brittle material. The results unify network glasses with other families of amorphous solids, such as bulk metallic glasses and glassy polymers, …

Amorphous Silicates -- Time-Current Superposition and the Dynamics of Plastic Flow in the Glassy State

Matthieu Bourguignon, Gustavo Alberto Rosales-Sosa, Yoshinari Kato, Sergio Sao-Joao et autres

Electron irradiation enables quantitative control over the plastic flow dynamics of silicate glasses, even far below the glass transition temperature. Through stress-relaxation experiments spanning ambient to near-glass-transition temperatures, we uncover a time-current equivalence that grants direct access to steady-state plastic flow over …

Fracture initiation in silicate glasses via a universal shear localization mechanism

Matthieu Bourguignon, Gustavo Alberto Rosales-Sosa, Yoshinari Kato, Bruno Bresson et autres

Shear bands lie at the root of fracture initiation in bulk metallic glasses and amorphous polymers. For silicate glasses, in contrast, studies have largely emphasized permanent volumetric strain, commonly referred to as densification. Here we systematically investigate indentation-induced fracture in two distinct …

Structural Changes upon Ambient Temperature Densification in Calcium Aluminoborosilicate Glasses: Relation to Indentation Crack Resistance

Yara Hellen Firmo Gomes, Gustavo Alberto Rosales-Sosa, Shingo Nakane, Yoshinari Kato et autres

Improving crack initiation resistance is an important objective of current glass research. High-pressure and indentation experiments are considered important predictors for the compositional design of glassy materials with optimized performances. For developing insights into the stress dissipation mechanisms, it is important to …

Structural Aspects of Ambient-Temperature Densification of Highly Crack-Resistant Borosilicate and Aluminoborosilicate Glasses: Two Case Studies Examined by Solid-State NMR

Yara Hellen Firmo Gomes, Millena Logrado, Tomiki Inoue, Shingo Nakane et autres

The structural aspects of ambient-temperature densification via pressurization at 25 GPa were studied by solid-state NMR for two case studies: An alkaline earth boroaluminosilicate glass with the composition 6CaO-3SrO-1BaO-10Al 2 O 3 -10B 2 O 3 -70SiO 2 (labeled SAB) and a …
