Experimental Measurement of rH Value in Two Stage Strain Paths
-
摘要: 應用Hill的準則,采用間接測量方法,得到了低碳鋼在兩次加載路徑中的平面各向異性系數rH。在所測數據ε1p和ε2p中呈現出線性關系。結果表明:rH僅為斜率K12的簡單函數,與ε1p值變化無關。在后繼拉伸實驗中,rH值是影響其力學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,ε1p and ε2p measured from the experiments, a linear relationship was observed. rH is as a simple function of the slope term, which is independent on ε1p.
