[en] 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.
