Abstract:

A ring-reinforced, orthotropic circular cylindrical shell subjected to external hydrostatic pressure loading is investigated. The stresses and deflections throughout the shell are determined by a shell theory which considers the combined and separate effects of large rotations, transverse shear deformation, initial deflections and Flugge type thickness terms. The ring deformations are described by both a deep ring theory and a plane strain analysis. The results are used in the development of pertinent design formulae. Numerical results applicable to a typical glass-reinforced-plastic shell indicate that the nonlinear effects may be accurately provided for by using a perturbation solution. Hills criterion for yielding of an orthotropic material as well as an analysis to approximate the actual stresses in the constituent materials of a nonhomogeneous shell are also applied.
