    Abstract

    Fracture toughness determination standards and procedures give limits for the measuring capacity of different specimen sizes and types. Numerical methods and local approach are used as additional means to determine the validity of the toughness estimates and provide toughness scaling criteria for integrity assessment. The current study contributes to this domain and presents experimental and numerical results of fracture toughness and tearing resistance of F82H ferritic stainless steel. Three-point bend specimens of sizes 3 * 4 * 27 mm, 5 * 5 * 27 mm, 5 * 10 * 55 mm, 10 * 10 * 55 mm and 25 mm compact tension specimens are tested in the temperature range of-196°C to room temperature, in order to determine and characterize the fracture properties of F82H and specimen measuring capabilities from brittle lower shelf cleavage to upper shelf ductile R-curve. The experimental results are used to calibrate local approach models, which are then further applied to determine the attributes and usability of the different small specimens.
