Paper Title:
Damping Properties of Viscoelastic Stiffened Laminated Cylindrical Shells with an Unconstrained Fiber-Reinforced Layer
  Abstract

By use of the mixed layerwise theories and the interpolation functions of displacements and transverse stress, the dynamics equations of viscoelastic stiffened laminated cylindrical shells with an unconstrained fiber-reinforced layer were derived. The predicted vibration frequency and loss factor show the good agreement with the A.Okazaki’ experimental results for the two-layer cylindrical shells. The non-dimensional frequencies and loss factors were computed for different Young’s modulus and thickness of viscoelastic layer. The results show that using a higher module and thickness viscoelastic layer can effectively increase the loss factors; moreover, using a circular-reinforced viscoelastic layer has little effect on the non-dimensional frequencies, but can effectively increase the model loss factors.
