Fracture Mechanics Tests with the Use of Miniaturized Test Specimens

Original language description

Determination of mechanical properties with the use of sub-sized specimens is a topic of high interest nowadays. The application of the sub-sized samples is quite wide for all cases where only limited amount of the experimental material is available such as evaluation of additively manufactured products properties, residual life of in-service components, properties determination of developed nanostructured materials, assessment of dilatometric samples used for thermal and thermo-mechanical treatment development, local properties of components, weld joints and so on. Concerning this large application field it would be very useful to prepare standard for small size samples especially for most demanded material properties: tensile properties, notch impact transition temperature, fatigue properties, fracture toughness and creep and so on. The current work is dealing with fracture toughness employing master curve and J-R curve approaches for fracture toughness parameters determination with the use mini specimens. The experimental material is reactor pressure vessel steel provided in the form of 2T-CT specimens. These specimens are tested and from the broken halves 1T-CT specimens are machined as well as mini Charpy specimens. Results of fracture toughness tests achieved for different size specimens are subsequently compared and the size effect in assessed.
