buckling deformation

The metal flow of slab in sizing was analyzed and the buckling and "fish tail" at slab head and end were studied with plastic collapse theory according to the mutual influence of end and deformation zone.

对减宽侧压过程的板坯金属变形流动情况进行了分析，并结合外端与变形区的相互影响，采用塑性失稳理论对板坯的失稳弯曲现象和头尾部鱼尾变形进行了研究。

It is found that the buckling strength of column-supported silos is mainly dependent on the height of the engaged column, which also affects the buckling deformation mode.

结果表明，支柱伸入高度是影响仓壁柱承钢筒仓轴压下屈曲强度的主要因素，屈曲模态也与之密切相关；

After deboned, the faceplates occurred the permanent bending deformation and elastic buckling in the vertical main direction of compression load, and the foam core happened the shear failure and permanent plastic deformation.

上下面板和泡沫夹芯脱胶分离后，面板主要垂直于压缩载荷的方向发生弹性屈曲和永久的弯曲变形，泡沫夹芯在冲击损伤的附近发生剪切失效和永久的塑性变形。

When residual stress overrides limit, plate will create destabilizing buckling deformation and billows.

当残余应力超过极限时, 将使板材产生失稳屈曲变形,出现波浪.

Deformation of helical buckling appeared on rod during down stroke is also analyzed.

同时分析了下冲程抽油杆所产生的螺旋弯曲变形.
