In performing design strength analysis of connection areas of composite — metal and composite — composite types of structural load-bearing wing and empennage elements of the aircraft implemented using mechanical fasteners, it is necessary to considerthe factors determining the local strength of these areas: the conditions of mechanical contact of the body, bolt head and cap with connected elements, the connected elements contact with each other and the effects of friction. These factors can be taken into account only by applying the global-local modeling approach for constructing 3D prediction models of composite — metal and composite — composite joint zones of aircraft caisson structural members. To solve this problem, a method is proposed defining the means and tools of modeling, algorithms for constructing a prediction model and performing calculations, as well as procedures for analyzing the results of calculations.
