Abstract
In this paper, the authors revisit the original Valanis model by investigating some characteristics of the model and propose a modified slip model to capture the hysteretic behaviour of the frictional contact interface. An identification approach is proposed to identify the proposed slip model parameters. This approach is examined using various numerical systems with different forms of nonlinearities typically used in known engineering applications. In addition, a simulated model of a bolted flange is considered to validate the proposed approach. The identification results show the capability of the proposed model to regenerate the forces at different levels of vibration. This indicates the validity of the proposed model in representing the nonlinear behaviour of contact interfaces in assembled structures. An experimental case study employing a bolted flange is considered to generate contact frictional forces and hysteresis loops. Finally, an experimental investigation of the experimental results is carried out.
