The dynamic response of joined structures, notably the amplification of vibrations, is strongly influenced by the characteristics of the joints. Bolted joints are non-linear both in stiffness and magnitude of energy dissipation, and structures assembled with bolted joints inherit these non-linearities. This largely experimental study shows how thin metallic inserts in the contact region may serve as a tool to alter the non-linear properties of the joint and in this way increase or decrease the level of equivalent viscous damping in the structure. Both quasi-static and dynamic measurements have been performed and a mathematical model trimmed to the static measurements has been shown to produce valid results also for dynamic simulations.
