Abstract
The concept of energetic mobility is presented; its use on a single structure and its use for an approximate prediction of the exchanged powers and of the local energies after rigid coupling, on an assembly is exposed. The concept of frequency averaged active power source is also proposed. Numerical simulations illustrate this method for two different homogeneous and heterogeneous substructures rigidly linked at several points.
