Abstract: Deformation under the action of normal separation of a composite plate consisting of two consoles connected by an adhesive layer in a state of flat deformation is investigated. From the general variational formulation, taking into account the Mindlin—Reissner theory, a differential formulation is obtained. An analytical solution obtained with complex roots of the characteristic equation of a system of second-order differential equations is investigated. Using the Tresca—SaintVenant criterion, the value of the external load corresponding to the elastic limit and the onset of plastic deformations in the adhesive layer was found.

Keywords: adhesive layer, composite, interaction layer, normal separation, elastic deformation, Tresca—Saint-Venant criterion.
