As the hazards of vibration and noise are known, there is an active demand for damping and denoising. Viscoelastic material is one of the important methods of vibration and noise control, and especially it is fit for the control of wider frequency and multi-peak resonant vibration. Due to the wide use of viscoelastic material in engineering to control the vibration and the appearance of new viscoelastic material in recent years, the dynamic problem of viscoelastic complex structures becomes more and more im...
