    Abstract: The end surfaces of large storage tanks used in various industries are often composed of thin-walled metallic spherical cap structures. The ability to process these components at a low cost and with high manufacturing precision is an important research challenge. In this study, a new integrated free-bulge forming method is proposed to fabricate thi... Show More
