Abstract: Problems of analysis and optimization of axisymmetric shells of piece wise constant thickness are studied. The cases of quasistatic and dynamic loading are considered separately whereas the shells may be manufactured from both, elastic and inelastic materials. Minimum weight designs of inelastic shells of piece wise constant thickness are established under the condition that the limit load is fixed. Also the designs of maximum load carrying capacity are determined for given weight (material volume) of the shell. Necessary optimality conditions are derived with the aid of variational methods of the theory of optimal control. Particular cases of maximization of the load carrying capacity of spherical caps and conical shells are studied in a greater detail in the cases of von Mises and Hill's materials.
