摘要：
The studies on theoretical modeling of a sandwich shell (SS) and sandwich beam (SB) are presented in this paper. The displacements of adhesive layers are computed in the whole SS. The Euler-Ostrogradskii equations are used to derive the equations of equilibrium, which contain six 16th-order differential equations. The three-point bending of a sandwich beam is considered and the behavior of the adhesive layer of the SB is calculated.
