RR207 - Review of low cycle fatigue resistance

The S-N method of fatigue life assessment is stress based, and is only fully applicable to cyclic
stresses in the elastic range. However, in offshore installations the presence of stress
concentrations at nodes and other connections can, in some circumstances, lead to cyclic
stresses that exceed the yield stress of the material locally. This study is aimed at reviewing the
current status of design advice and more recent experimental data with the objective of
evaluating the treatment of high stress ranges.
