Especially for subsystems with complex geometry and material may be desirable to use experimental or numerical methods to identify their parameters. In this paper is Finite Element Method (FEM) in combination with Power injection method (PIM) used for evaluation of coupling loss factors. Methodology is illustrated on several examples of connected plates and beams. Statistical and sensitivity analysis of this methodology is also presented.
