| Popis: | This chapter discusses the fracture toughness of reactor pressure vessel (RPV) materials as a consequence of service in a neutron irradiation environment. Fracture toughness of the materials is directly related to structural integrity of the operating RPV and the materials must be evaluated relative to their radiation sensitivity and effects on overall structural integrity. In radiation-sensitive steel, the fracture toughness is decreased and is the property used to describe the radiation-induced embrittlement. The chapter presents a brief history of the development of fracture mechanics followed by more detailed discussions of different aspects of material fracture toughness under both quasi-static and dynamic loading conditions. |
