ABSTRACT
This chapter describes hoop stress as it is applied to spheres carrying an internal pressure and apply the hoop stress formula to compute the maximum stress in the wall of a thin-walled sphere. It also describes longitudinal stress as it is applied to cylinders carrying internal pressure and apply the longitudinal stress formula to compute the stress in the wall of a thin-walled cylinder that acts in the direction parallel to the axis of the cylinder. The chapter identifies the hoop stress, longitudinal stress, and radial stress that developed in the wall of a thick-walled sphere or cylinder due to internal pressure and apply the formulas for computing the maximum values of the stresses. It offers a wide variety of standards, guidelines, and computational aids to ensure safe and economical design of pressure vessels. High-strength composite materials are well suited for use in fabricating pressure vessels.
