TLDR
In this article, the critical stress intensity factor, crack velocity-stress intensity relations for any glass can be predicted from the fracture stress and fracture surface mirror of specimens tested in 3-point bending.Abstract:
An analysis has been presented which enables the critical stress intensity factor, crack velocity-stress intensity relations for any glass to be predicted in a very simple manner from the fracture stress and fracture surface mirror of specimens tested in 3-point bending. A comparison of fracture energies and crack velocity parameter calculated from the mirror data with measured values supports the accuracy of the method.read more

Kalyan Kumar Phani,A K Maitra +1 more
TL;DR: In this paper, generalized relations between the strength distribution function and derivatives of the fracture probability have been obtained for cylindrical specimens tested in 3-point bending and derived relations have been used to evaluate the probability of failure during dynamic loading using a fracture mechanics approach.

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.

TL;DR: 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.

A method for evaluating the time-dependent failure characteristics of brittle materials — and its application to polycrystalline alumina
TL;DR: A simple method for evaluating stress intensity factor, crack velocity (K, V) diagrams is described in this article, which is applied to the alumina/water system and the K, V diagrams are used to predict times to failure and effects of strain-rate on strength.

Fracture Surface Energy of Glass
TL;DR: In this article, the double-cantilever cleavage technique was used to measure the fracture surface energy of six glasses and the results ranged from 3.5 to 5.3 J/m2 depending on the chemical composition of the glass and the temperature of the test.

Subcritical Crack Growth in Ceramics
TL;DR: In this paper, a design technique is presented to predict useful component lifetime from crack growth data after proof testing, based on fracture mechanics concepts, and the available crack growth is discussed with particular emphasis on fracture mechanisms.
