Abstrakt: Cast manganese steel predetermined for container casks of spent nuclear fuel has been tested extensively from the point of view of resistance against brittle fracture. For the fracture toughness evaluation the three-point bend specimens with different crack length (varying a/W ratio > 0,5; 0,2; 0,1) and with the same ligament below the crack tip have been used. Stress distributions below crack tip have been calculated by finite elements method (ABAQUS code) for each specimen geometry separately. Modification has been introduced into calculation taking into account specific material behaviour.
