FATIGUE PERFORMANCE UNDER MULTIAXIAL LOADING; REPT. FOR MAY 88-MAY 89

The environmental loading and structural geometry associated with welded marine structures often produces multiaxial stresses. Large scale welded details have been used to characterize multiaxial fatigue response in marine structures; however, cost of these tests is often prohibitive. A review of multiaxial fatigue literature was performed to identify analytical techniques that might be used to predict multiaxial fatigue response. Various approaches are identified and summarized. Supporting literature is referenced. The reliability (bias and scatter) of the multiaxial approaches is presented where available. Various factors influencing multiaxial fatigue response are identified. A welded detail is used as an example to show how multiaxial fatigue life predictions are obtained from uniaxial fatigue test data. Finally, research is recommended to facilitate the technology transfer of multiaxial fatigue research to marine structures.
