Rivets are widely used in several industries including aerospace, shipbuilding and construction. Aircraft components such as wings and fuselages are some examples of riveted structures. Accurate parameter identification of these joints is critical since excessive number of rivets is present in such structures. Furthermore, modeling structures with fasteners has always been a challenge since these members might show nonlinear behavior. In this study, the FEM of a continuous plate is constructed and modal tests are performed in order to have a valid modeling strategy. After a good correlation between finite element analyses (FEA) and tests is obtained, a finite element model with riveted joints is constructed and parameters of these fasteners are identified by means of vibration measurements and optimization.
