      Inert ion-driven convergence of viscoplastic cylinder and sphere shells is investigated. An equation of motion for such finite-thickness shells is derived. The comparison made between kinetic-to-thermal energy dissipation rates shows that spheres have a higher dissipation rate than cylinders. The contribution of viscous and plastic properties to the kinetic energy dissipation is illustrated. Analitical and numerical results obtained may be used to analyze an inertion-driven convergence of shells and also to test complicated numerical procedures.
