This study presents the results of a study of cases of a combination of strength and deformation of the inner layer of a plate and a shell, which have different physical and mechanical properties or whose outer layers consist of layers that are resistant to aggressive media. The monograph presents theoretical and experimental studies, introductory conclusions, an analysis of the literature used, the results of a study of the stress-strain state of two-layer plates and two-layer shells. When considering the cases of deformation and stress of a two-layer combined cylindrical shell, the outer...
