Abstract:For the mathematical description of the yield behaviour of elastic-plastic materials the von Mises yield criterion proves to be suitable for the interpretation of the stress and strain curves of metals. However, many materials exhibit a pressure-sensitive yielding. These material properties are not adopted in the von Mises yield criterion. Hence a generalization of the yield criterion is necessary to examine pressure-sensitive materials. In this contribution, a generalization of the von Mises yield criterion i… 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.
