Abstract
Although edge-wave and centre-buckles in rolled strip are believed to be largely self-equilibrated, the result of residual stress, formation of herringbone and quarter-buckles in hot- or cold-rolled strip is believed to require application of external stress. It is verified here that stress distributions such as those indicated by Roberts are possible causes of quarter-buckling and herringbone buckling. Quarter-buckling is believed to result from stress in the sheet or strip produced by non-parabolic bending of the work rolls. Herringbone buckling is attributed to local regions of axial tension and compression in the transverse stress distribution, caused by misalignment, which effectively produces a shear in the sheet that may manifest itself in diagonal buckling.
