Strain Transformation

释义 Definition

“应变变换/应变坐标变换”。在材料力学、弹性力学与连续介质力学中,指把某一点的应变分量从一个坐标系(或某一取向的平面/方向)转换到另一个坐标系(或另一取向)下的计算方法,常用于求任意方向的正应变与剪应变主应变(principal strains)等。(该术语也可更广义地指“应变在不同表示之间的变换”,但最常见是坐标旋转下的变换。)

发音 Pronunciation (IPA)

/stren trnsfrmen/

例句 Examples

Use strain transformation to find the normal strain on a plane rotated by 45 degrees.
使用应变变换来求旋转 45° 后该平面上的正应变。

In composite design, strain transformation helps convert measured strains into the material’s principal directions for accurate stiffness predictions.
在复合材料设计中,应变变换有助于把测得的应变转换到材料主方向上,从而更准确地预测刚度。

词源 Etymology

strain 源自古法语 estreindre(“拉紧、束紧”),与拉伸变形的含义相关;transformation 来自拉丁语 transormare(“改变形状/形式”)。合起来,“strain transformation”直译为“应变的形式/坐标改变”,即把应变从一种方向或坐标表示转换为另一种表示。
