A variational approach to the study of the stress state of layered shells and plates with interphase defects is proposed. A variational equation was considered from which equilibrium equations and static boundary conditions on parts of external surfaces, kinematic joint conditions on conjugation surfaces were obtained. The problems for a two-layer plate with a boundary interlayer crack and an edge zone of plastic slippage are considered. The influence on the stress state of the mechanical and geometric parameters of the plates is analyzed. References Dundurs, Dzh., Komninou, M. (1979).
