TESTS OF MACHINED MULTILAYER SPHERICAL SHELLS WITH CLAMPED BOUNDARIES UNDER EXTERNAL HYDROSTATIC PRESSURE

Abstract

Six spherical shell models with clamped boundaries consisting of two and four layers were tested under external hydrostatic pressure to explore the feasibility of multilayer construction for application to hydrospace vehicles. In addition, four monolithic models were tested to provide a basis of comparison. Three of the multilayer shells were bonded with epoxy resin and the remaining three were not bonded. The bonded multilayer shell models collapsed at pressures approximately equal to that of the monolithic shells. The unbonded shells showed appreciable reduction in strength.
