Abstract

The locus of this paper is the formulation of an optimization technique for the design of prestressed multi-ring containers taking in account the mechanical characteristics of materials and a maximum internal pressure. For a cylinder with the same elastic constants as the shrinking rings, the dimensions of a prestressed container arc determined as a function of the allowable stresses of the liner and internal pressure. In this papa the design objective is to keep all the stresses within the elastic limit under operating conditions.
