摘要: 通過彈塑性有限元對幾個典型品種鋼管微張力減徑過程中的壁厚變化作了計算分析,并與實驗結(jié)果進行對照,證明用彈塑性有限元分析微張力減徑過程是可行的,并得出一些結(jié)論,這對于用有限元手段開發(fā)新品種,推廣微張力減徑技術(shù)有重要的意義。Abstract: Computing analysis of the in-process gage variations of several representative types of steel tubes being slight-stretch reduced via elastoplasticity finite elements is conducted, and comparison of the analysis with the experiment results made, showing that it is practical to analyze the steel tube slight-stretch reduction process with elastroplasticity element. The work done will greatly contribute to developing new product with FE method and disseminating the steel tube slight-stretch reduction technique
