Abstract
The results of an Internordic co-operative project are
described. A standard spectrum for fatigue testing is
proposed. It simulates the long term wave action history
to inertia dominated structures in the North-Sea.
Facilities for crack growth testing using the proposed
spectrum have been developed and used in comparative
tests. The results are realistic and reproduceable in all
the three participating laboratories. The spectrum test
results were well comparable to the constant amplitude
test results at high AK values, but the results indicate
that lower crack growth thresholds can be obtained by
spectrum loading in air.
