    Abstract

    J-R -curve testing is costly and difficult. The results may also sometimes be unreliable. For less demanding structures, J-R -curve testing is therefore not practical. The Charpy-V-notch test provides information about the energy needed to fracture a small specimen in half. On the upper shelf this energy relates to ductile fracture resistance and it is possible to correlate it to the J-R -curve. Here, a simple power law description of the J-R -curve was correlated to the CVNUS energy. This new correlation corresponds essentially to a 5 % lower bound and conforms well with earlier correlations, regardless of the definition of the ductile fracture toughness parameter.
