Abstract : The elastic deformations of a short, flexible, tapered ring under axisymmetric edge loading and uniform pressure are investigated. The ring is treated as a thin cylindrical or conical shell of short length and linearly varying thickness. A modified Geckeler-type approximation is used for the conical shell. Equations are derived for the elastic behavior of some typical shell junctures utilizing insert rings with tapered sections. A numerical example is given which indicates that maximum discontinuity stresses in a typical reinforced cone-cylinder juncture would be reduced by 33 percent by use of a flexible, tapered ring. The additional highly localized stresses due to notch effects have not been considered. (Author)
