“…Annealing to 500°C was found to significantly reduce this degree of alignment. Quach et al (2004) carried out an analytical model study, validated against a finite element study, to predict the residual stresses induced by the coiling, uncoiling and leveling of carbon steel material; an extension to this study was carried out by Quach (2005) for stainless steel sheet material. It was assumed that annealing occurred prior to coiling and therefore there were no residual stresses present in the sheet material before this coiling began.…”

The influence of residual stresses on structural members is to cause premature yielding and loss of stiffness, often leading to deterioration of load carrying capacity. Knowledge of their magnitude and distribution is therefore important for both structural design and finite element simulations, and hence extensive studies have been performed on structural carbon steel components. With greater emphasis now being placed on durability and reducing consumption of resources, the use of stainless steel in construction is growing, heralding the need for a more precise understanding of its structural response. Stainless steel exhibits differing physical and thermal properties from carbon steel, both of which influence the formation of residual stresses, and it cannot simply be assumed that residual stress models for carbon steel are also appropriate for stainless steel. This paper examines all existing data on residual stresses in stainless steel sections, including that generated from a recent experimental program carried out at Imperial College London and summarized herein. The collated residual stress data have been used to develop models for predicting the magnitude and distribution of residual stresses in press braked, cold rolled, hot rolled and fabricated stainless steel structural sections.

“…The physical and thermal properties of stainless steel differ from those of carbon steel, hence residual stress patterns and magnitudes arising in structural sections may differ [28]. A number of studies have involved the examination of residual stresses in cold-formed stainless steel sections [29][30][31][32][33][34] whilst fewer have addressed welded stainless steel sections [35,36]. The studies of Lagerqvist and Olsson [35] and Bredenkamp et al [36] focused on welded I-sections, where the residual stresses in austenitic, ferritic, and duplex stainless steels were examined.…”

Despite growing interest in the use of stainless steel in construction and the development of a number of national and regional design codes, stainless steel is often still regarded as only suitable for specialised applications. This is partly due to the high initial material cost associated with the most commonly adopted austenitic grades. The initial material cost of stainless steel is largely controlled by the alloy content, in particular the level of nickel, which is around 8% -10% for the common austenitic grades. A recently developed grade, known as lean duplex stainless steel (EN 1.4162), has a far lower nickel content, around 1.5%, and hence lower cost. Despite the low nickel content, it possesses higher strength than the common austenitic stainless steels, along with good corrosion resistance and high temperature properties and adequate weldability and fracture toughness. The structural performance of lean duplex stainless steel remains relatively unexplored to date with only a few studies having been performed. For this reason, an experimental and analytical research programme investigating the structural characteristics of lean duplex stainless steel was initiated.The present paper summarizes the laboratory tests performed on lean duplex stainless steel welded I-sections. The experiments include material testing, stub column tests and

Abstract. The aim of this research is to evaluate the through thickness residual stresses distribution in the walls and in the corners of a cold-formed open section made of a material presenting a non linear hardening behaviour. To get results as close as possible to the reality, the complete process is modeled, including coiling and uncoiling of the sheet before the cold bending of the corner itself. The elastic springback after flattening as well as after final shaping are also taken into account. In order to validate the model in predicting the residual stresses distribution, the presented results are confronted to experimental measurements and FE results collected from the literature.
