Rapid, catastrophic propagation of cracks is described in terms of stress concentration and energy balance conditions from a fracture‐mechanics viewpoint. Slow crack propagation by stress corrosion or other mechanisms is also presented in fracture‐mechanics terms. Data on slow crack propagation and accompanying acoustic emission in a variety of ceramics and glasses are reviewed. A survey is presented of the application of these results to the quantitative treatment of strength, dependence of strength on loading rate, time to failure, proof testing, acoustic emission monitoring, thermal shock, impact damage, and erosive machining. Some limitations in the application of fracture mechanics to ceramics are discussed.
