Gellin S, and Pauletti RMO., “Necking limits of conoid membrane structures with variable stress ratio”, Proc. 7th IASS-IACM Symposium 2012, Ibrahimbegovic A (ed.) 2012
ABSTRACT: The problem of the equilibrium shape of a membrane structure between two coaxial rings of identical elliptical shape separated by a specified distance with a fixed ratio between the meridianal and circumferential stress is explored. The maximum separation between the rings for a given stress ratio is determined, as well as the associated reduction in cross-section at the mid-plane between the rings. Results are compared with those obtained for circular rings.
