Abstract Mode I fracture mechanics has been relatively mature but mixed mode fracture mechanics continues to present challenges, in particular for ductile materials under multiaxial stresses. Since most engineering materials, e.g., metals, exhibit elasto-plastic or ductile behaviour and are subjected to inclined cracks and/or multiaxial loading, there is a well justified need to establish a solid understanding of their fracture behaviour under mixed modes. The intention of this paper is to criti...

Abstract Unloading compliance method (UC) and normalization method (NM) are two of the most commonly used methods for determining the fracture toughness of steels. Since the NM has been recognized as the most practical method there is a need to evaluate its accuracy against the classic UC method. This paper intends to investigate the factors that affect the agreement between UC and NM, including material mechanical properties, specimen thickness, the ratio of initial crack length to width ( a 0 ...

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...

Porous band at the steel-concrete interface in reinforced concrete can significantly affect the corrosion-induced cracking process of concrete. The quantification of this porous band is of great significance for accurate prediction of service life of corrosion affected concrete structures. In this paper, the effects of concrete design parameters, namely water to cement ratio, aggregate size and concrete cover, on the thickness of porous band at the steel-concrete interface are quantitatively inv...

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...

Mild steel is one of the most commonly used materials in the construction industry throughout the world, but it is also very vulnerable to corrosion in aggressive environments. There is little research on how corrosion and the hydrogen released from the corrosion process affect the mechanical properties of the corroded steel. The intention of this paper is to present results produced from a comprehensive experimental program designed to investigate the effects of corrosion and corresponding hydr...

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...

Although corrosion of metal in soils has been intensively investigated in the past, a review of the published literature shows that limited research has been undertaken to understand how soil properties affect the corrosion behavior of cast iron pipes, owing to the scarcity of the reported information on buried metal corrosion in its backfill soil condition. In this paper, a methodology is proposed to statistically analyze the effects of soil properties on corrosion behavior, and a comprehensive...

Deterioration of reinforced concrete (RC) structures is unavoidable after their long time in service, with corrosion being the major mechanism of deterioration. In order to ensure safety of deteriorated structures, an effective rehabilitation plan is essential. Although considerable research on strengthening of RC structures using fibre-reinforced polymers (FRPs) composites has been undertaken, more is on the methods of strengthening and effects of corrosion on strength of RC columns than that o...
