成形路徑對鋼板織構成形極限的影響

Change of Texture Under Different Strain Paths and Influence on Forming Limit

摘要: 完成了沖壓過程中可能出現的幾種應變路徑(單向拉伸、等雙向拉伸、單拉-等雙拉、等雙拉-單拉路徑)和不同應變量共14種狀態的極圖測定,分析了各種情況下織構的變化,討論了材料取向的變化對于復雜路徑成形極限的影響。

Abstract: The work, tests 14 pole figures for steel sheet under some strain paths, i.e. tension, equibiaxialstretching, uniaxialtension-equibiaxialstretching and equibiaxialstretching-uniaxialtension, and different strains. Texture influence on forming limit is discussed.
