Abstract : A review is given of the present state of our knowledge of the brittle fracture of ceramics. This includes discussions of the theoretical strength of solids, the Griffith theory, and the role of dislocations. Other topics covered are effects of environment, stress distribution, microstructure, and Weibull's theory. It is concluded that, although we are not yet able to quantitatively predict the behavior of ceramics in engineering structures, the available theoretical and experimental information can be useful as a qualitative guide for the development of ceramics with improved properties, as well as design of components, and for reduction of the number of proof tests required.
