ANALYSIS FOR DETERMINING STRESSES IN STIFFINED CYLINDRICAL SHELLS NEAR STRUCTURAL DISCONTINUITIES

Abstract:

Recent developments in structural research on circular ring-stiffened cylinders subjected to hydrostatic pressure have indicated that refinements of the standard strength analysis are required to account for the effects of discontinuities such as a heavy frame or bulkhead or variations in shell thickness. A procedure has been developed for computating axisymmetric stresses near these discontinuities in a cylinder in which the thickness of the material does not vary between a pair of stiffeners but may change from one side of a stiffener to the other. The results of this analysis indicate that stresses higher than those predicted by a standard computation will usually exist near these discontinuities. A method of reducing this effect by modifying the geometry near these points is also presented.
