TLDR
In this paper, it was shown that a crack front increases its length by changing its shape when it interacts with two or more inhomogeneities in a brittle material, and an expression for the fracture energy was obtained.Abstract:
Observations are presented showing that a crack front increases its length by changing its shape when it interacts with two or more inhomogeneities in a brittle material. These observations are presented for both cleavage and conchoidal types of fracture. Based on these observations and the concept that a crack front possesses a line energy, an expression for the fracture energy is obtained. This expression shows that the fracture energy should increase as the distance between the dispersed inhomogeneities is decreased. Using the Griffith fracture criterion, this result is discussed for the case of strengthening a brittle material.read more

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.

LXXV. The moving griffith crack
TL;DR: In this article, a straight crack moving through an elastic medium is calculated and the stresses depend on the velocity and reduce to Inglis' solution when the velocity is zero, and the results may be applied to the spicular fracture of glass.
