Residual stresses in cold-formed steel members: Review of measurement methods and numerical modelling
https://orcid.org/0000-0003-4964-5128
Abstract 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.
Highlights Experimental measurement of residual stresses in cold-formed members is reviewed. Sectioning, hole drilling and X-ray diffraction are the most common techniques. Residual stresses due to press braking can be predicted using analytical approaches. Roll forming modelling requires simulations that are computationally challenging.
