Fracture, Static Fatigue, and Reactions of Water with Glass.
Abstract
The main aim of this project has been to learn more about the fracture of glass, particularly as it is affected by reactions with atmospheric water that are accelerated by tensile stress. Delayed failure of soda-lime glass and a glass ceramic were studied in detail, leading to a new theory of static fatigue in glass and discovery of the only known oxide showing no static fatigue. Crack lengths were measured by a new etching technique, which also provided a measure of the crack tip radius and an experimental test of the Griffith Fracture Equation. A discussion of criteria for brittle fracture developed from this work.
