Experimental and numerical modeling of flatness defects in

Increased forces during the rolling induce higher deformation of the rolls and consequently a heterogeneous thickness reduction over the width of the strip. Then, compressive residual stress appears, and elastic wave buckling can be expected at the edges or the center of the strip . It is thus important to understand the relationship between residual stress and wrinkling for better control of the
