Connecting bond switching to fracture toughness of calcium aluminosilicate glasses
Sidsel Mulvad Johansen, Tao Du, Johan F. S. Christensen +5
Fracture toughness is a critical mechanical property of glasses, but a detailed understanding of its link to composition and structure is still missing. Here, focusing on the indus…

In situ mapping of indentation-induced densification and cracking in vitreous silica by nanofocus X-ray scattering
Johan F. S. Christensen, M. Faizal Ussama Jalaludeen, Søren S. Sørensen +9
The practical strength of oxide glasses is greatly reduced by surface flaws that form during processing and use. Instrumented indentation can mimic such real-life damage events and…

Transferable potential for molecular dynamics simulations of borosilicate glasses and structural comparison of machine learning optimized parameters
Kai Yang, Ruoxia Chen, Anders K. R. Christensen +4
The simulation of borosilicate glasses is challenging due to the composition and temperature dependent coordination state of boron atoms. Here, we present a newly developed machine…
