摘要
如何描述变形体内过一点微段的线应变总是受到人们的关注,文章使用变形几何学分析了线应变的计算,指出线应变是转角的函数,证实小变形假定不仅要求变形小,而且要求转角小的结论。
It has always caught people＇s attention, how to describe the line-strain of a small stretch of deforming body, which passes a point. Using deforming geometry, the paper analyses the calculation of line-strain. It points out further that line-strain is the function of rotation angle, and proves the conclusion that small deformation hypothesis requires small deformation and small rotation angle.
