In this paper, a modeling strategy is proposed in order to identify the behavior of a two-node finite element connector. This connector is substituted for a complex three-dimensional bolted joint. A first connector model has been proposed and implemented in a user-element subroutine in ABAQUS CAE. Connector model identification was performed on an elementary single bolt joint under tensile and compressive loads. The result is a fine scale three-dimensional computation obtained using a mixed domain decomposition method which shares similar features with the augmented Lagrangian formulation in order to efficiently account for frictional contact conditions. It is shown that the dissipated energy as well as the cumulated displacement jumps between the parts of the assembly are in good agreement with the three-dimensional numerical simulation.
