ABSTRACT
Thin-walled circular cylinders appear in a number of different branches of engineering, including ocean engineering, aeronautical engineering and civil engineering, and in food packaging, boiler technology and medicine. In ocean engineering, such structures include submarine pressure hulls, offshore drilling rigs and other submersibles. In aeronautical engineering, such structures appear as fuselages for aeroplanes and rockets. Here only pressure vessels subjected to internal pressure are considered, because pressure vessels imploding under external pressure are generally of a postgraduate nature and are covered elsewhere. This chapter shows to: define a thin-walled pressure vessel, calculate the hoop stress in a thin-walled circular cylinder under uniform pressure, and calculate the longitudinal stress in a thin-walled circular cylinder under uniform pressure. It also shows to: calculate the membrane stresses in a thin-walled spherical shell, under pressure, understand volumetric stress and strain, determine the additional compressible liquid that can be pumped into a thin-walled pressure vessel.
