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. 0263-8231 http://hdl.handle.net/10259/5670 10.1016/j.tws.2020.107335 Cold forming Residual stress Sectioning Hole drilling X-ray diffraction Numerical modelling Residual stresses in cold-formed steel members: review of measurement methods and numerical modelling
