Modelling of on line manifest flatness defects in thin strip cold rolling is addressed as a problem of buckling under residual stresses. The latter are stresses built beyond the roll bite by the rolling process itself. To this aim, a buckling / post buckling model has been developed, giving strip shape, amplitude and stresses, based on Damil and Potier-Ferry's method and hereafter named MSBM like Multi-Scale Based Method. Its input is a post-bite stress map computed by a rolling model. Simplifications of the buckling model make it amenable to a series of 1D FEM solutions, but restrict its application to simple flatness defects such as wavy edges or wavy centre. In a decoupled version, it has been successfully compared with literature result...
