Finite-element Analysis and Experimental Research of In-process Gage Variation of Steel Tube Being Slight-stretch Reduced

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
