虽然人们认为轧制带钢的边浪和中心浪在很大程度上是自平衡的，但热轧或冷轧带钢中残余应力的结果，人字形和四分之一波纹的形成，被认为需要施加外部应力。本文证实了Roberts所指出的应力分布是引起四分之一屈曲和人字形屈曲的可能原因。四分之一屈曲被认为是由工作辊的非抛物线弯曲产生的板或带中的应力引起的。人字形屈曲归因于横向应力分布中的轴向拉伸和压缩的局部区域，这是由不对准引起的，其有效地在板中产生剪切，这可能在对角屈曲中表现出来。
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.
