Abstract:Currently, structural integrity safety cases are based on avoidance of fracture initiation, providing a pessimistic estimate of structure life. However, crack behaviour at heterogeneous junctions is an area where understanding is particularly limited. Improved data regarding the behaviour of defects at such junctions after initiation may lead to improved assessment of real structures containing welded joints. Furthermore, justification of stable tearing at a material interface would result in increased demonst… 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.
