Abstract:Understanding spring back for the arched tubes constitutes a major problem for every tube manufacturer. Even when the allowable fluctuations are limited to tenth of degrees, angular fluctuations of several degrees are usually observed. This indicates the importance of the problem. The aim of this study is to understand the role of materials in determining spring back characteristics of bent tubes. The first stage of the work thus consists in finding analytical, semi-analytical, numerical or even empirical mode… 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.
