title = "Identification of a stochastic model for bolted joints",
abstract = "In this paper an FE model of the contact interface in a bolted structure is considered. The paper demonstrates how the uncertainty may be represented in the contact interfaces and investigates these uncertainty effects in the dynamic responses of the structure, e.g. natural frequencies. The contact interface is modelled using stochastic material properties to account for the variability in contact parameters, i.e. surface roughness and preload effects. A simplified stochastic dynamic model is then used, and the parameters of the uncertain joint model are identified based on simulated data. The maximum likelihood method is used for identification.",
