| 摘 要： | 应用Hill的准则,采用间接测量方法,得到了低碳钢在两次加载路径中的平面各向异性系数r~H。在所测数据ε_1~p和ε_2~p中呈现出线性关系。结果表明:r~H仅为斜率K_12的简单函数,与ε_1~p值变化无关。在后继拉伸实验中,r~H值是影响其力学性能的重要因素之一。

| Abstract: | The plane anistropic paramater (rH) of low carbon steel sheet in two stage strain paths was measured using Hill's Criterion,e1p and e2p measured from the experiments, a linear relationship was observed. rH is as a simple function of the slope term, which is independent on ep1. |
