Abstract
The purpose of this paper is to present a brief outline of the conceptual stage of the design of a special type multilayer pressure vessel with spaced shell-layers, and interlayer metallic cushions (CMV). Basic formulations for preliminary stress analyses, and estimates of the ultimate capacities and failure modes are given. The results of the analysis of a preferred model pressure vessel indicate that for the postulated thermal and pressure transients substantial reductions in stresses are possible for this type of vessel, as compared to conventional single wall or uncushioned multilayer vessels of comparable size, dimensions, and materials. The indicated failure modes are implosive-ductile, and the ultimate dynamic capacities for the CMV are larger than for comparable single wall or uncushioned multilayer vessels.
