Abstract:This paper presents the identification of dislocation-density-based crystal plasticity parameters for a A508 Cl3 bainite steel in non-irradiated and irradiated states and at different temperatures. The representative volume element for the identification process is a cube containing 1000 steel grains represented by a Voronoi mosaic discretized by finite elements. The grains are assigned crystallographic orientations corresponding to an isotropic texture. The crystal constitutive model is based on a plastic flo… 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.
