Abstract
Techniques are described which widen the application of the Griffith method for studying brittle fracture and which improve its accuracy. Methods are given for the evaluation of the intensities of semielliptical surface flaws which can be used for fracture flaws of the size and type found in commercial glassware. Techniques are described for scoring flaws of this character. This revised method is used experimentally to study the effects of various glass treatments on breaking stress. Data on stress fatigue are used to compare the specific fracture energy at fatigue limits with conventional values of surface energy. Other data on fracture velocity obtained from the stress–fatigue curves are used for the critical review of a recently proposed theory of stress fatigue.
