Abstract:
An experimental study, together with evaluation of relevant theory, is conducted of the damping action at the support interfaces of beams which incorporate visco-elastic bonding material. The objective of the study is the identification of support junction damping techniques which might be of practical use in vibration attenuation. It is found that the highest energy dissipations are associated with flexure and rotation of the beam ends embedded within the support structure.
