摘要：

An improved analytical model for the axisymmetric stress state of an adhesive joint of two cylindrical shells is proposed. The adhesive layer acts in shear and cleavage. It is assumed that the tangential stresses vary linearly across the thickness of the adhesive layer. The two-parameter Vlasov-Pasternak model of an elastic foundation is used to describe the normal stresses in the adhesive. The approach proposed makes it possible to satisfy boundary conditions at the load-free butt of the adhesive layer and to describe the stress state of adhesive with a high accuracy. The closed-form solution is obtained. A model problem is also solved.
