Conclusions 1. The typical feature of the joints with guaranteed tension is the high nonuniformity of distribution of the stresses on the contact surface and the presence of stress concentration zones. 2. The stress concentration on the surface of contact interaction of the components determines the formation of zones of fatigue failure, i.e., cracks, areas of fretting corrosion, excess metal at the ends of the components, etc., leading to premature failure of the joints with tension in operation. 3. The determination of the SSS of the joint with tension and the selection of its design and technological parameters which makes it possible to reduce the level of stress concentrations in the joint are associated with the formulation and solution of the contact problems of the theory of elasticity and plasticity for bodies of complex configuration. 4. The approximate solution of the contact problem for the joint with tension can be obtained using the finite element model of conjugate components with contact connections applied to the model. The tension in the joint and relative slipping of the components are simulated by means of the field of the hypothetical initial strains. 5. Experimental verification confirmed the satisfactory accuracy and reliability of the results of calculations in the proposed method of determining the SSS of the joints with tension.
