EN The paper is devoted to a sandwich circular plate consisting of two facings and a core with variable mechanical properties. The simply supported plate is compressed in the middle plane. The mathematical and physical model of the plate is formulated, and also the field of displacements. The system of equilibrium equations is derived basing on the principle of the total potential energy. Then the system is approximately solved. Three formulas for an unknown function of displacements are assumed. The solutions (critical loads) are compared and presented in Figures and Tables.
