The shape and size of the distortional area are related to the scanning path.

由于板料成形中只受热应力作用，变形区域的形状、大小与扫描路径有关。

Local and distortional buckling are important buckling modes for cold-formed thin-walled open sections.

局部屈曲和畸变屈曲是冷弯薄壁开口截面重要的屈曲模式。

In the problem of how to judge distortional buckling, a good method is use load-axial displacement curve.

在畸变屈曲的判断标准的问题上，可以采用荷载—轴向位移法，亦可以采用荷载—横向应变法。

As one of the strength-governing modes for cold-formed channel columns, distortional buckling is receiving more attentions.

畸变屈曲作为控制冷弯薄壁卷边槽钢柱承载力的重要模式之一，正逐步受到国内外研究人员的重视。

The use of the free undamped normal modes is seen to ensure that the linear and angular momenta of the distortional motion vanish.

看来采用自由无阻尼正规模态可保证变形运动的线动量和角动量为零。
