AbstractAbstract In this paper two methods used to satisfy the boundary conditions in the case of an open complete rotating ring are considered. It turns out that for smaller ratios of radii the collocation method yields better results than the moment method.Keywordsstress concentrationopen complete rotating ringcollocation methodmoment methodGet full access to this articleView all access options for this article.Get accessReferences1.
