摘要
本文对在大变形大转动情况下,变形梯度张量的各种分解理论进行了对比,并用图解几何法将描述应变与转动的各种量的意义和相互关系直观地表示出来,提出可变形体中刚性转动计算的图解几何法。
In this paper the comparisons are made for various theories of deformation gradient tensor decomposition in the case of deformation with a large rotation. A graphic geometric method is used to show intuitively the significances of various quantities describing the strain, the rotation and their mutual relations. And the author proposes a graphic geometry method calculating the rigid rotation of each point in a deformable body.
