Abstract

In this study, modeling methods for viscoelastic material are reviewed to investigate the vibration characteristics. Frequency response functions are obtained by employing experimental modal analysis and compared with the modeling results from a commercial software NASTRAN. Properties of equivalent model of the beam with damping material are also calculated by using the RKU equation.
