Abstract In this paper, the combined effect of corrosion and fatigue on the fatigue strength of steel connection plates is thoroughly investigated through a comprehensive experimental program. A model for fatigue strength degradation as a function of corrosion rate is developed. The mechanism of fatigue strength degradation is also examined to gain a insightful understanding of fatigue strength degradation under simultaneous corrosion and fatigue environments. It is found in the paper that the s...

Abstract A rare opportunity has been seized to study the corrosion effect on fatigue strength of steel after service for 128 years. This paper presents a comprehensive experiment on degradation of fatigue strength of steel under simultaneous natural corrosion and service loading. Fatigue tests, tensile tests and microstructural analysis are carried out, and the mechanism of degradation of fatigue strength of corroded steel is examined fundamentally. Relationship between fatigue strength, corrosi...

Abstract Steel structures are usually subjected to simultaneous corrosion and service loads which are cyclic in nature. This paper proposes a new methodology for prediction of fatigue failure of steel structures subjected to simultaneous corrosion and fatigue stresses. A model is developed to determine the effect of corrosion on S-N curve of steel subjected to corrosion and fatigue and verified with experimental results. The fatigue damage to steel is modelled as a stochastic process allowing fo...

There is little knowledge on the effect of stress on corrosion rate of mild steel and as to how the combined effect of stress and corrosion affects the mechanical properties of mild steel. This paper presents a comprehensive experiment to provide evidence of the effect of stress on corrosion progress and mechanical properties of corroded steel. Test specimens, both stressed and non-stressed, are immersed in hydrochloride acid with acidity ranging from 0.00001 Molar to 3 Molar. Cause and effect r...

Abstract This paper presents the discovery of the most severe form of corrosion induced degradation of steel – delamination. The causes and effects of preferred corrosion of steel are quantitatively determined through a comprehensive experimental program and detailed analysis of steel microstructure. A large number of simulated corrosion tests are conducted by immersing steel in acidic solutions to acquire new understanding of the corrosion process of continuously cast steel. Three microstructur...

Abstract This paper investigates the effect of corrosion on degradation of mechanical properties of G250 mild steel. Corrosion tests are conducted by immersing steel into hydrochloride acid solutions, with acidity ranging from 0.00001 M to 3 M. Both macro analysis and micro analysis are undertaken to investigate the mechanism of corrosion induced degradation of mechanical properties. Intergranular corrosion is found for mild steel during corrosion. Results indicate that there is considerable red...
