eng Abstract:
Complex analysis of fracture behaviour for low carbon manganese steel intended for fabrication of large containers of spent nuclear fuel (SKODA) has been carried out. Two locations, surface layer and central part, of the thick-walled plate have been followed in order to evaluate the material fracture resistance of full-scale cask segment. Fracture toughness data were determined for two different loading rates. Two specimen geometries, standard ones and subsized Charpy type specimens have been applied for the investigation. For dynamic loading two calculation procedures of dynamic fracture toughness determination have been applied, the first one arising from quasistatic approach and the other based on concept of dynamic key curve method. The transferability of results received on the small pre-cracked Charpy specimens was analysed and applied with good results.
