This paper put forward a semi-analytic semi-numeric method to analyze the cold bending of the hubcap.

该文提出一种半解析半数值的分析方法，对汽车轮辋挡圈的冷弯过程进行了分析。

The medium plate produced by Anyang Steel has stripe type silicate inclusions, which is the direct reason of cold bending.

安钢生产的中板普遍存在着条带状的硅酸盐夹杂，这是引起中板冷弯开裂的直接原因。

B. in a later chapter, hollow plate the smallest bending radius is 175 times of its thickness, can only cold bending, hot bending.

在后面章节中，中空板的最小弯曲半径是其厚度的175倍，只可以冷弯，不能热弯。
