摘　　要：通过弹塑性有限元对几个典型品种钢管微张力减径过程中的壁厚变化作了计算分析，并与实验结果进行对照，证明用弹塑性有限元分析微张力减径过程是可行的，并得出一些结论，这对于用有限元手段开发新品种，推广微张力减径技术有重要的意义。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
