The purpose of this paper is to present a methodology for the determination of the stiffness when using simplified substitutive model of the joint. The usage of detailed finite element (FE) model of the joint in complex assemblies is not convenient; therefore, the substitutive model of the joint is used in FE models.

    Design/methodology/approach

    The detailed and simplified FE model of the joint is created in ABAQUS software and the analysis as well. The results of displacements are used for the determination of the stiffness of connecting element in simplified substitutive FE model. The approach is presented based on the general view on the different regions in the joint.

    Findings

    A simple FE modelling approach for the joint including the equivalent stiffness is presented. The particular solution is performed for Magna-Lok type of the rivet. The results show the same displacement for the detailed and simplified FE models. The analytical formula for stiffness determination in the load case with minimal secondary bending is introduced.

    Practical implications

    The approach for stiffness determination is straightforward and so no stiffness “tuning” is necessary in the simplified FE model.

    Originality/value

    The new approach for definition of simple FE model of the joint is introduced. It is not necessary to model a complex structure with detailed joints. The equivalent stiffness can be determined by presented procedure for every joint without limitation of the type.
