Thin Cylindrical and Spherical Shells


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 ...
