Abstract : The purpose of this program was to develop and substantiate a theoretical method for accurately predicting the critical buckling strength of externally pressurized cylinders fabricated from filament reinforced plastic laminates and to determine the optimum construction for such cylinders. Cylinders representing various configurations of four different types of construction were fabricated and tested. The critical buckling pressure under hydrostatic loading and the elastic constants influential in buckling considerations were determined from the test cylinders and rings cut from them and compared with theoretically calculated values for each configuration.
