Fracture in glass and ceramic materials occurs from defects like machining or mechanically produced cracks, pores, and inclusions. Although actual defects are not necessarily regular in shape, they usually can be idealized by macro-cracks. Fractographic analysis of glass and ceramic materials has played an importantrole in our understanding of the mechanisms of failure of these materials. The real power of fracture surface analysis is in utilizing the fracture boundaries that form outside the flaw to describe fracture behavior, regardless of the flaw shape.
