The possibility of improving the damping capacity of cantilever strips by using high-damping inserts has been studied experimentally. Results are presented for an aluminium strip with solid and annular inserts of three different materials: namely, cast iron, bakelite and perspex. First, the material damping characteristics of all the four materials have been determined. These have been calculated from the specimen damping obtained from the free vibration records of cantilever strips. It has been shown that with a proper choice of insert material, considerable improvement of damping capacity can be attained by using very little of the high damping material.
