Abstract:In this paper the results of both friction coefficient and springback testing using a drawbead test are presented. Deep drawing quality steel sheet (DC04 according to EN 10130:2009 standard) was used as the test material. The experimental investigations were carried out using a special device that allows a change in the degree of deformation of the sheet metal on the drawbead. The friction tests were carried out for different values of tool surface roughness, specimen widths and degrees of sheet deformation. T… 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.
