【Abstract】 Computing analysis of the inprocess gage variations of slightstretch reduced thick steel tubes via elastoplasticity finite elements method is conducted, and comparison of the analysis with the experiment results are made. It is shown 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.更多还原
