Abstract
We are interested in the modelling of the damping at the level of the junction between two substructures. We model the connection by a meta-model which takes into account both dissipative and non-linear aspects of the connection. We use the Bouc-Wen meta-model. This model is adapted to be able to be inserted into a finite elements model. We obtained a non-linear dynamical system, which can be solved in the time domain with a Runge-Kutta algorithm. A software tool corresponding to this method is developed. To decrease calculation costs, we reduce the size of the system by a Craig-Bampton method. We present an application on an academic test-case, and also a comparison with experimental results.
