GENERAL INSTABILITY OF CIRCUMFERENTIALLY STIFFENED SANDWICH SHELLS SUBJECTED TO UNIFORM EXTERNAL PRESSURE

Abstract

The Bresse equation for the buckling of rings under radial pressure is modified to predict the general-instability collapse pressure of cellular sandwich shells under hydrostatic pressure. The validity of the equation is demonstrated by implosion experiments with carefully designed cellular sandwich shells, the general-instability collapse pressures of which are compared with the results obtained by the modified Bresse equation. The results indicate that the modified equation predicts the general-instability collapse pressure of cellular sandwich shells within 5 per cent. This equation is recommended for use only when the ratio of shell ring depth to shell mean diameter is less than 0.1.
