It is often said that "steel is an inherently ductile material," and yet this statement fails to explain how steel occasionally behaves in a brittle manner. This lecture examines brittle fracture from a holistic perspective, considering the many variables that lead to brittle fracture. Four case studies are used to illustrate the effect of these variables: the World War II Liberty Ships, the Silver Bridge, the Martha Ingram barge and the Hoan Bridge. The role of material toughness, loading rate, temperature, constrain and notches are examined.
