Measurement Method of Broadband Dynamic Characteristics of Viscoelastic Material for Compliant Coating

An improved method to measure the dynamic viscoelastic properties of elastomers is proposed. The method is based on the analysis of forced oscillation of a cylindrical sample loaded with inertial mass. No special equipment or instrumentation other than the ordinary vibration measurement apparatus is required. Typical measurement of the viscoelastic properties of a silicone rubber Silastic ® S2 were measured over the wide frequency range
