This paper presents a closed form analysis of behavior of a metal-lined composite sphere under internal pressure. Generic behavior, away from discontinuities, is considered. The composite is assumed to be linear elastic throughout, with transverse isotropy with respect to a radius vector. The liner material is elastic-plastic with assumed linear strain hardening. The analysis utilizes the J2 incremental theory of plasticity and is structured so that a typical pressurization history can be described, with proof, release, and cyclic pressurization. Numerical results are presented. The solution is used to relate performance with design parameter variation and design efficiency charts are presented.
