Fatigue testing using offshore load spectrum

Jussi Solin, Povl Bröndsted, Tor Slind

    Research output: Book/ReportReport


    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.
