The aim of this paper is to investigate the distribution of stresses due to expansion of a spherical cavity at the center of a non-homogeneous metallic sphere of finite radius for an elasto-plastic solid under an increasing internal pressure, the external pressure remaining constant. The non-homogeneity of the elastic material is characterised by supposing that the lame constrants very exponentially as the function of radial distance. The case of ideal plastic solid has been deducted from this general case.
