Bolted joint is an important component of any structure. It is used to assemble parts. However, these joints introduce non-linearity into the system due to the presence of friction at interface. The modelling of bolted joint is necessary to understand the behaviour of system. Microslip, macroslip and pinning of bolt shank with inner surface of through hole are some of the inherent phenomena of bolted joint when subjected to loading. To have better understanding of the response of joint subjected to sinusoidal loading, effect of above properties on energy dissipation is needed to be investigated. In this paper, we model above-mentioned properties using an eight parameters Iwan model. It captures change in stiffness at the inception of microslip as well as residual stiffness at the inception of macroslip. Pinning behaviour of bolted joint is also considered in this model. The proposed model gives more comprehensive details than previous Iwan-based models. The proposed model can be used to understand the dynamic behaviour of bolted joint beyond macroslip. © 2022, Springer Nature Singapore Pte Ltd.
