[more ▼] One of the fastest growing market segments for stainless steel is its use for cold-formed profiled structural members. It is wellknown that the forming process is likely to significantly enhance the mechanical properties of the profile by strainhardening. This leads to increased resistance compared to a resistance assessment based on nominal properties, even if this effect is partly counterbalanced by the introduction of residual stresses. It is thus necessary to be able to accurately determine its actual mechanical properties. For this purpose, experimental data and theoretical investigations aiming at determining the material behaviour of coldformed stainless steel profiles including the effects of the forming process are reported in this paper.

[more ▼] This paper presents a special thin-walled plane beam. nite element that accounts for the in-plane cross-section local deformation. The element is based on the superposition of a classical beam displacement field and of an additional field describing local e. ects, with an approximation on the local second-order membrane stress. eld. The theoretical formulation is summarized and an application of the resulting numerical tool to the post-buckling analysis of RHS thin-walled members with moderate local and global slenderness susceptible to both global and local buckling is then performed. Different types of analyses are presented (computation of critical bifurcation loads, geometrically non-linear analysis, geometrically and materially non-linear analysis). The results obtained with the proposed beam. nite element are compared to values provided by shell FE models.

[more ▼] 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.

[more ▼] This paper presents the experimental and numerical tests made on the Titanium based alloy Ti6A14V to identify its yield locus and the hardening behaviour. A bi-axial experimental equipment has been used to perform cyclic shear tests, simple shear tests and successive simple shear tests and plane-strain tests. Coupled with classical tensile tests, these tests enable to identify the yield locus and the hardening model. Teodosiu and Hu’s hardening law and isotropic Swift type hardening and kinematic Armstrong Frederick hardening models have been investigated.
