TLDR
In this article, the authors used fracture mechanics techniques to measure the crack velocities in water as a function of applied stress intensity factor and temperature, and apparent activation energies for crack motion were obtained.Abstract:
Stress corrosion cracking of six glasses was studied using fracture mechanics techniques. Crack velocities in water were measured as a function of applied stress intensity factor and temperature, and apparent activation energies for crack motion were obtained. Data were consistent with the universal fatigue curve for static fatigue of glass, which depended on glass composition. Of the glasses tested, silica glass was most resistant to static fatigue, followed by the low-alkali aluminosilicate and borosilicate glasses. Sodium was detrimental to stress corrosion resistance. The crack velocity data could be explained by the Charles and Hillig theory of stress corrosion. It is probable that stress corrosion of glass is normally caused and controlled by a chemical reaction between the glass and water.read more

The Mechanics of Earthquakes and Faulting
TL;DR: The connection between faults and the seismicity generated is governed by the rate and state dependent friction laws -producing distinctive seismic styles of faulting and a gamut of earthquake phenomena including aftershocks, afterslip, earthquake triggering, and slow slip events.

TL;DR: In this article, a linear-elastic fracture mechanics can be applied to describe the failure behavior of small flaws in ceramic materials, which is caused by the extension of small faults.

Influence of Water Vapor on Crack Propagation in Soda‐Lime Glass
TL;DR: In this article, the double-cantilever cleavage technique was used to observe crack motion and to accurately measure crack velocities in glass, where the measured crack velocity is a complicated function of stress and of water vapor concentration in the environment.

Stress Analysis of Cracks
Paul C. Paris,G.C. Sih +1 more
TL;DR: Elastic stress analyses of cracked bodies represented by stress intensity factor method - fracture mechanics as discussed by the authors, and fracture mechanics are used for fracture mechanics. But they are not suitable for fracture analysis.

Static Fatigue of Glass. I
TL;DR: In this article, a simple soda-lime glass has been investigated in relation to the sensitivity of this glass to atmospheric corrosion and an analysis of the failure process has been given which is based on the concept that inherent surface flaws grow by corrosive mechanisms to critical dimensions by virtue of a reaction between water vapor in the atmosphere and components of the glass.
