Numerical analysis techniques to support the Reliability of steel tube and pipe products

Numerical analysis techniques currently utilized to establish the reliability of steel pipe products are introduced. High reliability is required for steel pipes used as mechanical and structural components, such as automobile parts and line pipes, to ensure the product safety. To quantify the rupture strength of pipelines and the deformation behavior of steel pipes for cars during the secondary forming, numerical analyses are performed along with selected experiments at JFE Steel. Calculated figures have a good correlation with experimental results.
