The paper deals with simple analysis of deformation of cylindrical shells filled with the material of known unit weight. The aim of this article is to find a shape of such a shell as function of internal pressure and the height of cross – section. The solution is found with the help of numerical methods. The obtained results are of some importance in the analysis of sand-sausages. They were compared with Silvester’s ones ( 1986) and a good agreement was ascertained.
