Abstracts:
The elastic deformation of a composite plate consisting of two cantilevers connected by an adhesive layer in a state of plane deformation is considered. The stress state of the layer is considered on the basis of the characteristics averaged over the thickness. From the general variational statement, taking into account the theory of Mindlin—Reisner, a statement in a differential form is obtained. It is shown that in the stressed state of the layer there is a practical coincidence of two average principal stresses acting in directions orthogonal to separation. It has been established that the value to which the product of the specific free energy and the layer thickness converges at a fixed external load and the adhesion layer thickness tends to zero does not depend on the mechanical properties of the adhesive.
