The determination of residual stress distributions in cold-formed members is revisited considering both experimental and numerical methodologies. Destructive, semi-destructive and non-destructive techniques are reviewed with special emphasis on sectioning, hole drilling and X-ray diffraction; the particularities of each procedure on cold-formed sections are addressed. Theory on metal strip deformation and roll design is exposed before analytical and incremental closed-formed expressions are presented and compared to experimental results for press-braked sections. Finally, the most important works on finite element simulations of roll forming are revisited, highlighting the computational limitations and the capability for predicting residual stresses.
