Brittle materials such as ceramics and glasses break from a variety of causes and often without warning. Fractography is a powerful tool to analyze and interpret the fractures, and in many respects, is easier to do with brittle materials than with metals, polymers, or composites. This lecture will present the fundamentals for fractographic analyses of brittle materials and show examples of practical problem solving ranging from kitchen glasses to missile nosecones. Fractography can take the guess work out of why things break. It can reveal the true cause of fracture and surprise designers and modelers.
