Influence of Water Vapor on Crack Propagation in Soda‐Lime Glass

Abstract

Results of a new experimental approach to static fatigue of glass are presented. Using the double‐cantilever cleavage technique, it was possible to observe crack motion and to accurately measure crack velocities in glass. The measured crack velocity is a complicated function of stress and of water vapor concentration in the environment. Experimental results are discussed with reference to current theories of static fatigue.
