HYDROSTATIC TESTS TO DETERMINE STABILITY AND STRESS CHARACTERISTICS OF STIFFENED CYLINDERS WITH QUASI-TUBE INSERTS,

Abstract

Four aluminum models were tested under external hydrostatic pressure to study the structural stability and stress distributions in ring-stiffened cylinders supported with quasi-tube inserts. Test results for the geometries studied showed that the quasi tubes decreased the collapse pressures of the cylinders only 6 percent. Stresses in the cylinders were increased up to 63 percent. Comparisons between existing theoretical formulas for collapse pressures and experimental values for models with and without quasi tubes indicate agreement within approximately 7 percent. (Author)
