| 摘 要： | 本文用实验验证了对于两种中强度，低韧性的材料18MnMoNb10MnMoNbVCu，Ernst分离函数原理P＝g（a／W）H（△P／W）仍适用，并由此用实验标定了两种材料的浅裂纹试样的g（a／W）表达式，在此基础上，得到了浅裂纹试样塑性位移与载荷的函数关系式。

| Abstract: | This paper proves the Ernst's principle of separable function is still suitable for the two kinds of material named 18MnMoNb and10MnMoNbVCu which have medium strength and low toughness,and calibrates the expression of g(a/W) for the two kinds of material,Baseed on it,the function form of pl..ti.' displacement-Load is obtained. |
