Abstract:A new peridynamic (PD) model for crevice corrosion damage is introduced and cross-validated with experimental results reported in the literature. The model defines a simple metal ion concentration-dependent corrosion rate along the metal-electrolyte interface. Crevice problems have ratios of gap-to-length of 1/100 or lower. To increase the computational efficiency when having a domain with an extreme aspect ratio, the PD formulation with spherical horizons is modified to accommodate arbitrary-shape horizons. … 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.
