TL;DR: In this article, it was shown that, for almost all metals and alloys, a particular stress and strain will be required to form persistent slip bands, and that dislocation motion is reversible and there is no mechanism for fatigue.
99 citations
TL;DR: In this article, an exponential stress function that relates the effect of mean stress on the fatigue strength and life is presented, which is based on the premise that mean stress directly affects fatigue strength coefficient σ′f, of the Basquin stress-life relation.

TL;DR: In this article, the structural properties of galvanized steel wires were investigated and the fracture surface was found to be caused by corrosion fatigue rather than hydrogen embrittlement, which indicates that hydrogen brittleness is unlikely to occur.
98 citations
TL;DR: In this article, the authors quantify the influence of defect on the fatigue limit and show that the gradient of the hydrostatic stress is a good parameter to characterise the influence on fatigue behavior.

Abstract: : Fatigue cracks in steel ships often occur at welded joints where stress concentrations due to the joint geometry are relatively high and the fatigue strength of the weld is reduced in comparison to that of the base metal. This becomes more critical in ships built of High Strength Steels (HSS) because the fatigue strength of steel in the a welded condition does not increase in proportion to the yield or tensile strength. In many cases, the fatigue performance of severely loaded details can be improved by employing good detail design practices, for example by upgrading the welded detail class to one having a higher fatigue strength. In some cases, however, there may be no better alternatives to the detail in question and modification of the detail may not be practicable. As an alternative to strengthening the structure at a considerable increase in costs, procedures which reduce the severity of the stress concentration at the weld, remove imperfections, and/or introduce local compressive stresses at the weld can be used for improvement of the fatigue life. Similarly, these fatigue improvement techniques can be applied as remedial measures to extend the fatigue life of critical welds that have failed prematurely and have been repaired. To date, weld fatigue life improvement techniques have been successfully applied in several industries. While there has been increasing interest in the application of fatigue life improvement techniques to ship structures, at present there is a lack of guidance on the use of such techniques for design, construction and repair. Hence the key elements of this project were to compile available data on fatigue life improvement techniques, assess the feasibility and practicality for their application to ship details, identify gaps in the technology, and finally to recommend design, construction and repair requirements.
