TITLE:

”Structural Perspective on Fracture in Oxide Glasses”. 

ABSTRACT:

One of the main drawback of glasses is their tendency to break if sufficient force is applied. This may compromise the usefulness of the glassy product, which poses an incentive for developing more damage resistant glass formulations. In order to facilitate a more efficient design of more damage-resistant glasses in the future, fundamental research concerning the brittle fracture mechanism and what governs it, is needed. In this thesis, the fracture behavior of glasses, specifically oxide glasses, are investigated from a chemical point of view. The aim of this work is to shed light on the correlation between chemical composition, the structural characteristics dictated by the composition, and the resulting mechanical properties.
