Analytical model for fatigue life prediction based on fracture mechanics and crack closure. J.B. Ibso and H. Agerskov. J. Construct Steel Res., May 1996, 37(3), 229--261.
The study reported is a continuation of five-year's experimental work on the fatigue life of offshore steel structures at the Technical University of Denmark. Concentration of this current work being on the theoretical determination of the fatigue life. Comparisons between theoretical and experimental results are included. Crack closure mechanisms are shown to be of paramount importance for the physical understanding and explanation of fatigue crack growth under various load conditions and under different stress states. Welding residual stresses, crack closure, stress concentrations and crack shape are shown to be factors of great importance and should in general all be included in fatigue life predictions of welded joints. 30 refs.
