| 摘 要： | 从希尔 (Hill)正交各向异性体二次屈服函数出发 ,可以导出厚向异性板应力强度 (等效应力 )与应变强度 (等效应变 )的两组表达式 ;本文讨论了采用两组不同表述方法的选择 ,并利用单向拉伸与双向等拉两种实验作了可比性的分析比较

| Abstract: | There are two mathematical expressions of stress and strain intensity for normal anisotropic sheet that are derived from Hill's quadratic anisotropic yield function.This paper analyses these methods comparability and gives a selection by checking the hydraulic bulge tests against the uniaxial tensile tests. |

| Keywords: | stress intensity strain intensity comparability |
