Abstract

In aerospace, nuclear power, and new energy vehicles industries, utilizing integrated metal components with extreme sizes and/or structures is crucial for achieving significant weight-saving, performance-improvement, and excellent reliability. These components, made from metal sheets, rings, or tubes, exhibit characteristics like ultra-thin, ultra-thick, ultra-large, ultra-long, ultra-high ribs, and large variable diameters. During plastic deformation in metal forming processes, defects such as ruptures, wrinkles, excessive strain differences, and unexpected weak performance areas are likely to occur due to the intersection of multiple effects in different research disciplines, including materials science,…
