High performance shaped charges require a perfect rotational symmetry and homogenity in structure. Therefore the density distribution of the explosive inside the charge has to meet the same specifications in order to obtain the desired geometry of the detonation wave. In this paper we present an analytical model which describes the density inside the charge as a function of the pressure and the friction between the tool surface and the granulate. The density distribution inside a cylindrical body has been calculated. The comparison with experimental data shows a good agreement.
