摘要：
The paper discusses a method of optimization of thick-walled shells on the basis of the solution of inverse problems theory of elasticity of inhomogeneous bodies. There are discussed the terms of equal-stress and equal-strength structures. The notion of efficiency ratio of equal-strength shell as the ratio of limit loads in heterogeneous and homogeneous shells. Constructed the model of a multilayer shell of polymer concrete for which the coefficient of efficiency is close to 2.
