Brittle Fracture
Under specific service conditions, steel structures have shown that steel could be sensitive to a fracture type called brittle fracture, especially if they contained welds. In order to measure steel resistance against brittle fracture, a test called the “Charpy test” has been introduced. The designation of steel qualities are given in the relevant parts of EN 10 025, where the steel quality classes are defined by fixing a minimum or guaranteed value obtained from the Charpy V‐notch impact tests at a specified test temperature. Brittle failure can be excluded by a proper choice of the material. EN 1993‐1‐10 provides a method for selecting such a material, for the different possible applications and service conditions. The chapter gives a complete overview of the function of the toughness temperature dependency. It shows the complexity of the computations associated with safety verification.
