Abstract
Fracture toughness transition behavior of C-Mn cast steel intended for fabrication of large transport and storage container for spent nuclear fuel (ŠKODA 440/84) has been investigated. The fracture resistance has been assessed using data from static tests of the bend CVN and pre-cracked (PCVN) specimens and from the axisymmetric notched tensile specimens. Local material parameters have been calculated using the Beremin approach. Accepting this approach to the analysis of local criteria for cleavage fracture the location su and shape parameters m were calculated using FEM techniques for notched tensile bars having various type of geometry. The first one was the tensile specimen with the same circumferential notch the same as for Charpy (CVN), the other three types were U geometry with radii 1; 0.7; 0.2 mm.
