Abstract: The problem of synthesis of a multilayer spherical shell with maximum damping of natural oscillations from a finite set of viscoelastic materials is considered with a limitation on weight. The necessary conditions of optimality are obtained, a computational algorithm is derived, and an example of calculation is presented.
