An invariant formula for the right stretchtensor rate is given by a differential method directly.
利用直接求微分的方法,给出了右伸长张量率的不变性表示公式。

Finally, through the approximate analysis, the approximate representation on the rotation tensor and stretchtensor is proposed.
最后通过近似分析,给出了在小变形中等转动情况下转动张量和伸长张量的近似表示。

According to the principle of the transverse stretchtensor of object and the optic lever arm magnifying, this article designed a case tester for Young's modulus.
