Abstract:This paper focuses on the wall reinforcement design of toroidal shells with openings. Five 304 stainless steel test models were manufactured, and geometric measurements, three-dimensional scanning, and hydrostatic tests were carried out. The scanning models were established according to the measured geometrical imperfections. Linear buckling analysis (LBA), geometrically and materially nonlinear analysis (GMNA), and geometrically and materially nonlinear analysis with imperfections (GMNIA) were used for numeri… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
