| 摘 要： | 本文基于Ｃａｕｃｈｙ平均转动的新近成果，给出一种变形和应变的近似分析方法，在此基础上讨论了Ｇｒｅｅｎ应变的近似表达式及其误差计，这些近似表达式在求解非线性力学问题中是常采用的，文中关于Ｇｒｅｅｎ应变常用近表达式的误差估计是严格基于小应变－中等或大转动变形的明确定义而获得的。

| Abstract: | In this paper, by using the results obtained in [1] and [2], an approach for approximate analysis of deformation and strain is given. The approximate expressions of Green strain which are usually employed in solving problems of nonlinear mechanics are discussed and their error measures are provided in the case of small-strainmedium and large rotation. |
