Abstract : Cold rolling is a metal forming process where strip of metal passes between two rollers and comes out
thinner. We present a multiple-scale asymptotic model of cold rolling. Assuming rigid perfectly-plastic
material and large rolls, we explain how to rederive and go beyond existing theories. Results agree well with
FE simulations, and suggest the origin of residual stress in the resulting strip. This modelling approach has
potential applications in many metal forming processes.
