TLDR
In situ atomic force microscopy experiments are reported which reveal the presence of nanoscale damage cavities ahead of a stress-corrosion crack tip in glass, which might explain the departure from linear elasticity observed in the vicinity of a crack tip.Abstract:
We report in situ atomic force microscopy experiments which reveal the presence of nanoscale damage cavities ahead of a stress-corrosion crack tip in glass. Their presence might explain the departure from linear elasticity observed in the vicinity of a crack tip in glass. Such a ductile fracture mechanism, widely observed in the case of metallic materials at the micrometer scale, might be also at the origin of the striking similarity of the morphologies of fracture surfaces of glass and metallic alloys at different length scales.read more

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.

Scaling properties of cracks
TL;DR: In this article, the morphology of fracture surfaces of various materials is reviewed and the observations are interpreted within the framework of models of lines moving in a random environment, which suggests that fracture of heterogeneous materials could be seen as a dynamic phase transition.
