AXISYMMETRIC ELASTIC DEFORMATIONS AND STRESSES IN A WEB-STIFFENED SANDWICH CYLINDER UNDER EXTERNAL HYDROSTATIC PRESSURE
Abstract
A theoretical analysis of axisymmetric elastic deformations and stresses in a web-stiffened sandwich cylindrical shell structure under external hydrostatic pressure is presented. The solution is based on the use of edge coefficients for plate and shell elements of finite length, and includes the computation of edge forces and moments arising at common junctures of these elements. Equations are given for computing numerically the longitudinal and circumferential stresses in the two coaxial cylindrical shells and the radial and tangential stresses in the web stiffeners between the two shells. No consideration was given to the discontinuity effects arising from rigid or elastic restraints afforded by contiguous bulkhead or adjacent shell structures. Thus, the analysis presented is applicable only to a typical bay of a web- stiffened sandwich cylinder of long length. A numerical example is presented to illustrate the use of the equations.
