Updating of uncertain joint models using the Lack-Of-Knowledge theory
We simulated a nonlinear multiple bolted joint with uncertain parameters. We develop a LOK model by using a linear model with the LOK theory. An updating of the LOK model is performed with the simulated data of the nonlinear model. The modeling of nonlinear uncertainties with a LOK model shows its efficiency.
