Abstract
An iterative method for calculating flanged connections in the finite element formulation is proposed. The essence of the proposed method is to separate the contact problem into a separate localized process that depends only on the initial distribution of forces from the main load on the flange connection. In the initial matrix of stiffness of unrelated bodies, a binding matrix of contact with elements of high rigidity is added. The calculation is performed in two phases: the first phase determines the movement of the actual loads on the second, through a vector of dummy reactions, iterative specified voltage at the contact surfaces. The results obtained by the proposed method are compared with the experimental results and with the approximate calculation method.
