This paper analyzes the interaction of external semi-elliptical surface crack and embedded elliptical crack in a longitudinal plane of a pressurized cylinder. No numerical solution appears to be available in the literature so far. The analyzed ratios of the crack depth to crack length (b S /a S and b E /a E ) are 0.25 and 1.0; the distance between both cracks (s 1 /b min ) ranges from 0.5 to 2.0. In total 24 crack configurations are analyzed and the stress intensity factors along the crack front are presented…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
