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.
