N2 - The investigation of the friction-induced nonlinearity in the contact interfaces of the joints is critical in assembled structures. On the other hand, in the experimental study of the steady state response of the system, controlling the excitation force and its higher harmonics is one of the known challenges in testing joints. In this paper a detailed 3D finite element (FE) model capable of simulating the microslip behaviour at the contact interface of a bolted joint is adopted. Due to the high computational cost of this model, a 1D equivalent model is also constructed for the bolted structure using beam and Jenkins elements to represent the effects of slip and slap behaviour in the contact interface. The equivalent model shows good performance in quantifying the energy dissipated due to damping compared to the 3D detailed model. In addition, to capture the friction behaviour in the contact interface due to micro-slip mechanisms, a set of experimental tests were performed where the hysteretic behaviour of bolted joints was investigated.
