DEEP OVAL RING EQUATIONS WITH SIMPLIFICATIONS FOR APPLICATION TO RING-SHELL COMBINATIONS,

Abstract

Equations which are applicable to deep oval rings in which the local curvature of an arbitrary reference line is prescribed are derived and simplified for application to oval ring-shell combinations. Theoretical estimates of the stresses and displacements are obtained for a typical reinforcing ring of a ringstiffened oval cylinder recently tested under hydrostatic pressure by the David Taylor Model Basin. These results are obtained by appropriately approximating the oval cross-section and by assuming that the composite structure responds as an oval ring. The theoretical flange stresses are shown to be in good agreement with available test results. (Author)
