Dissipation in mechanical systems plays an important role in limiting vibrationlevels. The present work deals with maximizing damping induced by junctions and treatsjunctions integrated into an overall structure. After introducing the physical models used inrepresenting viscoelastic behavior, a first example introduces the concept of coupling. Coupling,estimated by preliminary calculations of elastic natural frequencies sensitivity, ensures thatjunctions sufficiently contribute to the global behavior to induce damping. To study this couplingas well as obtain accurate damping predictions by complex modes calculation, model reductionmethods, adapted to parameterized problems, are needed and different strategies are detailedand validated.
