Thin Cylindrical and Spherical Shells

CHAPTER OBJECTIVES

Thin cylindrical and spherical shells are used mainly for storage of gas, petrol, liquid, chemicals, grains and so on. Some are subjected to internal/external pressures and the order of pressure is low (10–30 atmospheres). Their D/t ratio, that is, the ratio of diameter to wall thickness, is large, that is, D/t is greater than 20. Because in comparison to diameter, thickness is very small, so the variation of stresses along the thickness is taken negligible. In this chapter, we will learn about:

  • How to determine hoop stress and axial stress in a thin shell subjected to internal pressure.

  • How to determine axial, circumferential and volumetric strains in shell subjected to internal ...
