A hollow sphere of inner radius b and outer radius a is subject to normal pressures on its inner and outer surfaces. The sphere is made up of an isotropic material, the displacements and stress fields are spherically symmetric. The only non-vanishing displacement component is the radial displacement ur, and is a function of r only. Based on this we can assume the following strains. lu lur dr The only non-vanishing stress components are the radial stress σ, and the...
